Looks good to me. Does Xen have any sysexit/sysret32 equivalent to return to 32-bit user mode? If so, it could be worth trying to wire it up by patching the jz instead of the test instruction.
We can actually make patching a little bit more efficient by replacing the test instruction with 'xor %eax,%eax'. That way we won't need any 'nop's.
