I confirm that graphics run a lot more stable now, however, the issue is
not gone:

I had been working around the lockups by setting
  Option "DRI" "false"
  Option "Shadow" "true"
in my xorg.conf

Recently, I wondered if the problem still exists, and I removed these
lines. The machines ran quite stable in day-to-day life, but I could
still reproducibly crash the GPU running the demo of "celestia (Gnome)"
(part of the edubuntu package).

The weird thing is that after approx. one week, crashes started to
increase a lot, and I had to reenable the DRI/Shadow workaround. Note
that these machines are LTSP clients, all graphics goes across the
network.

I have the impression that GPU lockups occur when network traffic is
high, i.e., X needs to wait for graphics data more often.

All in all, things have improved a lot, but the problem has not
"magically disappeared". I don't believe it's fixed.

  This is a MASTER bug report, i.e. not a real bug report, but a tool to
  help manage other bug reports.

  Most bug reports on i845 are probably due to the CPU/GPU incoherency
  problem that is now consolidated upstream at
  http://bugs.freedesktop.org/show_bug.cgi?id=26345 . For now, we mark
  all automatically reported GPU lockups as duplicates of this unless
  there is a reason not to.

  
  To use the available fix, run the following commands:

  apt-add-repository ppa:glasen/855gm-fix
  apt-add-repository ppa:brian-rogers/graphics-fixes
  apt-add-repository ppa:glasen/intel-driver
  aptitude update
  aptitude install linux 855gm-fix-dkms
  aptitude dist-upgrade

  
  There is a similar master bug report for i855 at bug 541511.
