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.
