Howdy, I've got a 1.3Ghz (non overclocked) running on the SiS 735 chipset
(yes, the first good chipset from SiS) with no problems under 2.4.9 with
athlon optimizations, the system has DDR ram, and is used a lot for video
capture/compression, the avifile library detects (and supposedly uses) the
optimizations, and I've had no problems whatsoever with the system. Perhaps
this is another VIA problem.

As I write this a friend is repairing a lost partition on his FIC AZ11E 
motherboard (KT133 chipset), apparently due to a BIOS bug..
