Another couple of things to try:
 1. Specify 'noacpi' and/or 'ignorebiostables' on Xen's command line.
    This will cause parsing of some configuration tables to be skipped
    -- which may help if the BIOS is buggy.
 2. Let us know more hardware details (e.g. VIA chipset version). It
 would be useful to see the output of lspci ('lspci -vv').
