When I am using the sis driver and I load pages with a lot of images within
firefox, my system usually freezes within five minutes.  I have also had freezes
while running other applications but they are less frequent.  The system becomes
completely dead, and the caps lock key does not work.  I have no such problems
with the vesa driver.

I am currently running SuSE 9.2.  I previously had the problem under Kubuntu and
Gentoo.  I didn't check the drivers on the latter two so I can't be sure I was
using sis on those, but I assume that I was.
