Ahhh yes, you're right, IO-APIC only. My bad.

The messages on the kernel-list indicate that the source of the problem
seems to be timing issues when the CPU/memory/bus get faster than APIC.
If the overall speed of the machine is above a certain point, then the
problems start. That's why some people have problems and some don't.
Also a good reason why someone putting together a brand new machine
should be aware.

BTW, I really passed "noapic nolapic pci=noacpi" to the kernel. (No
typos this time.)

I would still buy the board, though, despite the problems I had getting
it set up. The sound and video are fine for what I'm using it for.
