I'm actually having problem booting 32-on-64 hvm guests.  Specifically 
the Fedora installer crashes fairly early on:

Freeing unused kernel memory: 280k freed
Write protecting the kernel read-only data: 844k

Seen anything like that?

Last I heard, they got something booting, but it wasn't very clean.  I 
need to resync with Eduardo.  A lot of these changes were intended to 
make that effort easier, but it would be nice to confirm ;)  Doesn't 
look like http://git.et.redhat.com/?p=xen-pvops-64.git;a=summary has 
changed much lately.
