Hmm, 2.4.2-ac28 and 2.4.3 have the same collection of VIA fixups in
arch/i386/kernel/pci-pc.c.  Something else must be causing this?

Did you run the .config through a 'make oldconfig' on each kernel, to
catch CONFIG name changes and so forth?

Does the BIOS have a setting that sounds like "System performance
setting" with choices such as "Optimal" or "Normal"? If so, try both
settings.  The terminology above is what is used on the ASUS A7V.

What would be quite useful, I think, is the output of 'lspci -xxx -s
0:0' under both the non-corrupting kernel (2.4.2-ac28) and the
corrupting kernel (2.4.3).  The output of 'dmesg' under both kernels
would also be good.

I find that a good way to present information like that, where most of
it should be the same and one is looking for the differences, is via
'diff -u --unified=1000 a b'.
