Yes the docs and driver for the graphic part of the sis630 suck (I
helped debuggin/hacking it ...) - but the sis735 runs rock solid here!
Using a mga450 and an Athlon XP1700+.

Here I only see one Athlon system crashing all the time. This is a
700Mhz Duron runnign in a Asus A7V. With a 2.4.16 kernel compiled with
Athlon optimization all applications are crashing all time (sed, cc,
gcc, sawfish - all. Simply sig-11), with a 2.4.4 kernel (using the
same .config) it seem to run just fine. 4 passes of memtest86 showed
no error, either ...

I see the broken via chips involved most of the time.

We will try a i386-only optimized kernel tomorrow.
