IA64 is a completely different architecture than x86.  Think gasoline vs.
diesel.  x86 and IA64 are not compatible at all.

If you were talking about amd64, that's a different story.  Most newer
CPUs are amd64.  All amd64 CPUs can also run a 32bit x86 OS.  Some x86
32bit CPUs are also amd64 compat.
