Under Xen 3.1, I''m able to use the ACPI Multiprocessor HAL (and the
uniprocessor one as well, when I only need 1 VCPU) or both 32 bit and 64
bit Windows.  Under 3.0.4, I''m pretty sure I was only able to use the
MPS Multiprocessor and uniprocessor HALs, along with the Standard PC HAL
(although I had to play with various settings), but not any ACPI HALs.
Sadly I can''t remember if this was with 32 bit or 64 bit Windows.

If you need/want multiprocessor capabilities, I really do suggest
upgrading to Xen 3.1.
