Hi!
I've been struggling with that problem... As far I've seen: 
   -When kdm is about to init (after starting/restarting the computer), there is some problem switching to X and the system gets hanged in variable forms: completely (only the computer's on/off button to scape), or garbage in the screen, or displaying low graphics dialog. Many times, when loading with kernel 2.6.31-15, was a complete hanged, unresponsiveness blank screen. I could at the end get the 'low graphics' dialog by loading previous versions of kernel 2.6.31-14 and 2.6.28-16. This required  sometimes not to delay to choose the console option or even the inferior part of the dialog dissapeared under the bottom of the screen after some kind of  automatic resolution change... in general, quite hazardous situations that may completely block access to the computer.
   -I thought at the beginning in the last Xorg upgrade, but the problem remained after downgrading. The same regarding the nvidia drivers (removing, reinstall).
   -Then started to play around in console mode: desinstalled kdm and gdm: startx loads correctly X with nvidia driver and so does startx /usr/bin/startkde ... but the sound is lost: Intel HDA audio is only accesible from root: aplay -l results in not finding file while sudo aplay -l detects correctly the audio (both in kde and gnome).
   -Then I reinstalled kdm: the original problem came back.
   -Removed kdm and installed gdm: the system starts correctly now, without any error and with the sound ok.
   -Noticed also that when the nvidia xorg driver loads it displays a fraction of seconds nvidia's logo: it happens with startx, startx /usr/bin/startkde and now with gdm... but not with kdm... so it looks like the problem is at some point between kdm and Xserver.
   -Another thing: just after reinstalling kdm, from console: sudo service kdm start, worked ok (even nvidia logo). But after restarting the computer... back to the problem, as described.

Best regards
