What are the symptoms there?  Is the guest still alive?  Is qemu-dm
alive?  Does it respond on the network, and just have a wedged console?
(Might it be the keyboard + mouse that have got wedged?)

Strange.  Are you doing anything wierd with the ioreq or xenstore pages
in the simple guest?  Their PFNs should have been maintained across the
first save/restore cycle, and they were mappable the first time...

Cheers,
