Thank you for your help - it pointed me in the right direction.  I was 
specifying acpi=off on just the dom0 Linux kernel.  Adding acpi=noirq to 
the Xen kernel instead seems to have worked around the problem.
It's quite a sad state of affairs when an Intel board with a 2 month old 
BIOS has such big ACPI problems - I thought the BIOS vendors had squashed 
most of them these days. :(
