Hm, actually backlights work at several Kiloherz frequency, but to be able to dim the backlight the off-cycles are made the longer the more you lower the luminance.
Frequencies in the region of 140 Hz are usually not discernable for the human eyes. In fact most people wont see any more flicker at 75 Hz with some people prefering 100 Hz. So as long as you ain't no jet-pilot oder grand-prix driver it's hardly a problem at all.
As far as I know TFTs "flicker-range" is about 100 Hz for dimmest setting to 400 Hz for nearly brightest setting. The brightest setting actually should not flicker at all, since the backlight is all powered up then, which also is often discernable by sound of the converters. But I am sure it differs from manufacturer to manufacturer and even from display to display.
That said I have to admit though that I know the Viewsonic VP2030 can produce backlight flickering when luminance is set lower than 5%. On the other hand it archives some really dark luminance settings which most TFT wont achive anyway. So you are always free to set it to a higher flicker-free luminance. Given the 10 bit LUT of the Eizo displays you can always lower the RGB-values to lower overall luminance without losing colors, too.
So while I cannot really judge on the quality of the Eizo backlight, I think there is something odd about your arguments.
According to that site the backlight uses a set rate at every luminance setting, and just increases the "off" time of the backlight which is well possible and makes sense. But still I don't see why 140 Hz should be more of a problem than 320 Hz. 140 Hz is already double as high as the perceptible frequency of around 70 Hz and it's 40 Hz more than what most people have been using for years on CRTs.
And CRTs do not use half-frame blinks as far as I can tell. They build a complete frame line by line, then the line vanishes to black before a new line is drawn. TV signal is build of interlaced half-frames but is as well displayed at full-frame rate as well (line drawn, line cleared, line drawn etc).
Regarding the S1910: it uses very large dot pitch of 0,297 mm. Some people have reported about eye strain and headache because of that.
Frankly I am absolutely with you that frequency should be as high as possble, but can the Samsung achive as low a luminance as the Eizo at such a high frequency? Most TFTs burn my eyes with their high luminance, so I am always happy to be able to set them as low as possible when I need to. I also wonder if a high frequency switching backlight will last as long as another one that is switched at a lower frequency (less often in a given time span).
142 Hz ist sehr genug.

Don't you belive - just look at your Eizo screen with videocamera set at sport mode.
Videocameras usualy only record at 30 frames/s or 25 frames/s, so what are we supposed to see?
I do understand you point, you actually you gave no facts that in anyway prove that in practice a flickering of 140 Hz is any much worse than a flickering at 320 Hz. I also wonder how the measurements of svethardware.cz are taken? Do they measure a single pixel, a single line or a whole area? Do they measure a stable picture (like all white) or do they use dynamic content which would have to take pixel switching time into account!?
Where are all the Eizo-users complaining about headache?
I´ve got the feeling you just discovered a list of numbers where a big company (Eizo) is listed with relative low values compared to other manufacturers.
Judging Eizo as a "very bad manufacturer" only based on a particular value which obviously has never been critisized by owners (and Eizo users are users that look closely) is a bit strange in my eyes.

We are hiding...
Every friday our anonymous 142Hz-flickering-group meets on a secret place.

Picture is nice at first sight , but if you look at it for long hours every day you will feel it.
Yes, I can feel that I had made a good choice when I bought my S1910 
Sometimes I sit more than 12 hours in front of the screen and I have absolutely no problems with that. Several ours of that (evenings->night) with only 10% brightness.
Yes yes yes, Eizos are flickering way too much. All the people over the internet and all users are wrong, they just don´t see the bad flickering. All the forums are giving wrong information about the great picture quality of Eizo TFT because 90% of the forum users are Samsung employees.
Maybe some Admin here can post your list on the main page of prad.de so that we all can see what crappy monitors have been recommended for the last couple of years.
When I´m at it: Did you know that all Maybach seats are uncomfortable because the springs are 2 cm too long? Noone knows so far, but I´ve got a document that says so. Damn, where is it, seem to have misplaced it...
Sarcastic mode off 
If your 1910 was flickering so strong that you could hardly stand it, it was broken. It´s just impossible that all other Eizo users just don´t see the flickering. There are occasional users, sure, but there are way more "professional" users who would definitely share their negative experiences in the internet. Be sure such information would be spreading like a virus, here (in the biggest German TFT Forum) as well. Now that it doesn´t, it can hardly be *that* bad. Right?
