Reverting back to 1.1.1-8 fixes the bug, right ?

Given that there are very few users of this driver, even among the
upstream devs, it would be very nice if you could locate which upstream
commit broke this. Looking at
http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-glint.git, I
guess the pciaccess port (Dave Airlie's commits) are the best candidates
for this breakage. Can you trying reverting these 4 patches and see if
the bug disappears? (reverting less than 4 may lead to build failure
from what I see in the logs).

Also, it would be nice if you could catch a backtrace with gdb. And even
better if you could catch a backtrace after rebuilding the driver with
debug enabled (see [1]) and installing xserver-xorg-core-dbg.

thanks,
Brice
