I am not sure about that. Andrew patches changed xen.gz size significantly.
My patches does not do that in significant way. They (precisely it) just
move load address from 1 MiB to 2 MiB. So, I do not expect major issues
here. However, anyway it should be tested (and it was tested, IIRC, by
Konrad some time ago).
