Yep, this is very likely broken because of the ABI changes for the 32-on-64
support done in xen-unstable a month or two back. Its on my list of things
todo, but not got around to it yet because Fedora 7 development was still
on 3.0.4 tree.

No work has been started AFAIK - anyone is welcome to take a stab at adding
support if they need it soon.
