That should be fine. That would at least give the user something easy to
search for (both web and source), and thus make it possible to at least
get an idea of why the boot is hanging for the few people that's going
to hit this.

For most systems, the default to load the initrd/initramfs below 4G (and
only load it above on the second attempt) will handle our buggy EFI's...

To me this sounds like something that should work.

Cheers,
Anders
