That's what we've got in common -- the VIA chip set. Nothing but trouble
with that, to be honest. Memory performance is slower than on 440BX chip
sets (trying to work out how to tweak the PCI registers with setpci so as to
enable memory interleaving) and the IDE interface works poorly.

Also discovered that there's an issue with the IO-APIC and Linux. If I
disable it (append="noapic" in lilo.conf or at the boot prompt), I don't see
the weird slowdown in disk performance.
