There is probably a BIOS issue (from reports I've seen on this issue),
however the git version of the xserver-xorg-video-intel driver does not
address a couple of crashes with 855 hardware which are caused by the X
driver writing registers in the card.

http://www2.eng.cam.ac.uk/~pcjc2/ubuntu/xserver-xorg-video-intel_2.1.1-0ubuntu10~pcjc2.2.diff.gz

Shows the diff applied to a (yet unreleased) Ubuntu package for the
drivers. (Applies against 2.1.1 release version). You should be able to
find the patches in the debian/patches/ dir which the diff creates.

It might be worth looking at these, and revisiting the BIOS issue if (as
is unfortunately likely) if there remains an issue.
