Ah, interesting. One thing to note (and which I've just noticed) is that 
it looks like this fixup is only called when you boot with the "linux" 
command and not with the "linuxefi" command. If you're using Ubuntu, 
"linux" may fall back to "linuxefi" without executing this fixup. So we 
need to add it to the kernel EFI stub anyway.
