Here's a few more...

d) Does it do it both with and without DRI enabled in the config 
   file (the Load "dri" line)

e) Are you using our official mga driver, or are you using the 
   Matrox binary driver and hallib

f) Are you running any 3rd party kernel modules at all, or using 
   VMware or other software which is sometimes known to cause 
   system instabilities

g) Are there any DRM or AGP errors in /var/log/messages
