This is not the VIA chipset, it's the "8259A interrupt controller".

First check out what kind of chipset you really have;
lspci -xs 0:0
should do the thing. Post the results.

In the meantime, you can try to compile for
"Pentium-Pro/Celeron/Pentium-II", and check your BIOS settings one more time
(set stuff to "safe" values). Also, do you have a really recent kernel, such
as 2.4.18? There were some changes in the Athlon/VIA "quirks" department a
while ago, but after 2.4.15 (i think).
