Comment 36 for bug 96430

I was bitten by this bug and have been beating my head against the wall over possibly another bug. I downgraded my 2.6.20-13 kernel to 2.6.20-12-lowlatency (With the kernel headers to match). apt-get remove --purge nvidia-glx cleared the restricted modules.

Well to make a long story short I reinstalled the older 9631 nvidia-glx package and older restricted-modules. Then attempted to reistall the drivers from nvidias website. No go... Why not?

Tried deleting everything nvidia wise and reinstall to no avail. Finally I tried the 2.6.20-12-generic and reinstalled again and everything works. So the 2.6.20-12-lowlatency kernel or kernel headers must be borked somehow.
