If your host CPU is 32-bit then there's no way of running a 64-bit guest using 
Xen - sorry. You could try Qemu (http://www.qemu.org) which is a full 
emulator and thus might be able to do what you want.
If you have a 64-bit CPU then you can (running a 64-bit Xen) run 32-bit *and* 
64-bit Xen guests simultaneously. You can even run a 32-bit dom0 ("host" 
operating system) but /Xen itself has to be 64-bit/, which means that 
your /hardware/ has to be 64-bit.
I hope this clears up any confusion. Please ask more questions if you're 
still unsure!
Cheers,
mark
