Bug 8554

I have a thinkpad x60 with an intel 945GM graphics controller, and I have
configured Xorg to use dual head. When I try to run glxinfo (or glxgears or any
other application using dri, such as xscreensaver), X crashes. If I use an
Xorg-configuration without dual head, dri works fine. I'm using Xorg 7.1 and
version 1.7 of the i810 driver.

The crash is reported in Xorg.0.log like this:
[...]
