I suspect that's because of some quirk of your mobo... Xen 2.0 is happy with
the CPU but tripping up because of some other hardware support. Ditto for
SuSE 9.3, which includes Xen 2.0 binaries.
Xen 3.0 uses different platform initialisation code to be compatible with more
systems - that's probably what fixed your problem. 32-bit Xen 3.0 would
probably be happy on your system too ;-)

There was talk of enabling SMP by default but it appears not to be the case in
the standard xen0 / xenU kernels. Make your own Xen kernel and it will
(probably) Just Work :-)
