I don't know - because I don't really know what's going on in your
guest, and unfortunatley, it can be VERY hard to figure out without
modifying the Xen-kernel to output extra messages... 

And some problems are common between Intel and AMD, others only occur on
one or the other.

As to changing distro, I don't believe that's the right way to go about
the problem - unless there's OTHER compelling reasons to change distro.
The side-effect of changing from one distro to another is that you get a
different version of Xen kernel. Since that's PROBABLY going to solve
your problem, I would suggest that you try the Xen-3.0.4-1 release from
xensource.com. That's a lot newer than FC6 uses - not sure what OpenSuSE
10.2 uses...
