The new openchrome xserver did not help. I updated and then ran several experiments, all with the same result:

1) 'Default" xorg.conf with no driver selection,
2) xorg.conf with explicit 'driver "openchrome"' selection
3) xorg.conf with explicit:

    driver "openchrome"
    options "EnableAGPDMA" "0"

   (I found a note someplace that this would help).

I verified the correct openchrome driver was installed using 'dpkg-query -s xserver-xorg-video-openchrome'. It reports version 1:0.2.903-0ubuntu2.

I've been trolling through /var/log/kern.log and /var/log/messages and I noticed that the last message emitted by Linux before the crash is always:

  [drm] Initialized drm 1.1.0 20060810

I looked around in LP for other DRM bugs but I don't see one that matches this failure mode. (Doesn't mean its not there, its just not obvious to me).

It's also possible this was the last successful operation and that its unrelated. I tried 'modprobe drm' while on the console in recovery mode (prior to starting X) and it loaded the drm kernel module w/o error. I also ran 'modprobe via' to load the kernel/drivers/gpu/drm/via/via.ko module and that also worked.

I'm out of ideas about where to look next...
