This won't help because Xen doesn't support x64 at the moment.

That would require that Xen supports PAE (accessing more than 4GB via
the MMU) and can run guest operating system which don't support PAE
(like NetBSD-i386) while using PAE.
I don't know about PAE support in Xen but the second requirement sounds
unlikely from what I know about the Xen architecture.
Kind regards
