Bug#491205: xserver-xorg-video-intel causes X to crash irrecoverably and without warning

[Peter Dey <pdey@realmtech.net>]

I experience the same symptoms on a Q33 chipset (X3100), too.  X crashes saying 
"fatal server error: lockup", th edisplay looks corrupt, then I'm booted back to 
a console.  I can't restart X, and can only do so after a reboot.

However, I have been able to semi-reliably reproduce the problem using the 
'osd_cat' program.  It doesn't crash *consistently*, but does crash say, 5 times 
out of 10.

Cheers,
Peter
