Err... 32-bit unmodified guests? Fully virtualized? Would this be with
the upcoming VT-extensions or would this be possible on any AMD64
available today? Or does Xen64 mean Xen on IA-64 (ie. Itanium etc.)?

If running unmodified 32-bit guests with reasonable performance on any
x86_64 host is possible, that would be an absolute killer feature.
