I also have an SMP system using VIA. Its an Asus dual coppermine, I
do not recall the exact board number.

I don't have a large variety of USB devices on it. But what I have used
works fine.

This motherboard does have an IOAPIC, so does not require the noapic
option.

One thing of note, there has been a bit of activity in the apic code recently,
you never did say what kernel version this was using, maybe a recent
vintage would help??

Merry New Year :)
