I've not tried Xen with AMD-64 myself, but I'd expect it to be fairly
good & certainly if there were significant issues they'd get fixed pretty
quickly, since basically all serious x86 server hardware these days is 
64-bit with 32-bit  going the way of the dodo. IIRC, the Intel chips with
virtualization extensions for example are all 64-bit. If you don't want
to experiment with upstream Xen, then best bet would be to just grab the 
Fedora Core Test-2 release when it comes out in a few weeks & run some
stress tests to see how stable the AMD64 is.

Regards,
Dan.
