Forgive me for jumping in here, but, in theory, it *should* be
possible to utilize a 64-bit domU kernel with a 32-bit userland,
assuming of course that the domU kernel has 32-bit compatibility
turned on.  In practice, getting the 32-bit userland set up might be
somewhat tricky, but this shouldn't be impossible.

Am I missing something?
