if you are up to experimenting:

1) find the patch I posted on list, apply it (note that the email had two 
attachements, you want only one)
http://article.gmane.org/gmane.comp.emulators.xen.devel/3669
http://sourceforge.net/mailarchive/message.php?msg_id=10116333

2) edit Rules.mk

3) add "nosmp" and "noacpi" to xen boot params,

... and see how far you get.
