I have to report that this bug does also affect other login-managers (well, one at least: Slim).
And I am using a Nvidia 9500gt video card - not an ATI. So it does not seem to have much to do with the video card actually.

I had the same problem: After an update with the automated update-manager yesterday and the following reboot I was left with the "low graphics mode"-error. 
_Sometimes_ clicking through "run in low-graphics-mode for one session" etc. led me to my normal login (with Slim). And I would even get a running Compiz... a bit surprising for the expected "low-graphics-mode"... but Compiz would silently die sometime in between and leave me without graphic-effects. 
Yet very often after reboot I was left without a login and only with scrambled colors on top of the screen or, even worse, a crashed system with a black blank screen where only turning power off helped!

I tried many possible solution-variations of tinkering with xorg.conf,
deleting and reinstalling the Nvidia-drivers etc. - all to no avail. I
was so sure that this had something to do with the updated kernel and
non-fitting or conflicting video-drivers...

But it was apparently a conflict between GDM and "the other login-manager" - in my case Slim, not KDM. 
Directly after deinstalling Slim and "dpkg-reconfigure gdm" the "low-graphics-mode" problem is gone.

Seems to me its _not_ KDM or Slim who are having the bug.
