Exactly which version of Xen are you running (copy of the output from
"xm info" would help!).

We test both 32- and 64-bit versions of Xen when we make our
contributions to Xen-source, so it _SHOULD_ work. Of course, sometimes
we'll miss something in one direction or the other [I mostly develop on
a 64-bit base, so I personally know that my changes work on 64-bit
systems, but before it's submitted to Xen-Source, all changes should be
tested on 32-bit systems too], there's certainly no INTENTIONAL
differences. But since 64-bit version of Xen was a bit flaky early on,
the first version of Xen to work on SVM was the 32-bit version - so
since I saw that you got the 32-bit version working, perhaps you're
running an older version of Xen... 

Also, not so long ago, SMP-version of the Hypervisor would cause all
sorts of problems, but it's been fixed for several weeks at least... Xen
changes very much from day to day...
