The domU kernels are xenlinux, and 32-bit xenlinux does not run on a
64-hit Xen. The patch is supposed to fix 32-bit _unmodified_ guests
support (e.g. native Linux, Windows, etc.) on a 64-bit Xen when the H/W
virtualization technology is present.

32-bit userland apps are supposed to run in x86_64 xenlinux today.
