Last I checked, Athlon XP's weren't certified for SMP, only MP's.
That's likely what the problem is. And for the record, Tyan also makes
Intel boards too.

Processor manufacturing 101: All processors of a given family come off
the same production line. Due to variations in the process, some
processors have defects that only show up at higher clock speeds, SMP
mode, etc. At the end of the line the processor is tested. If it fails
at higher clock speeds it is marked at a lower speed. If it fails SMP
it is marked as an XP. Market demand can also cause a chip to be rated
lower than it really is, so you can sometimes get away with
overclocking, etc. but it's just random luck if it really works.
