EFI has a pretty interesting specification we can read about. Unless
they've done something exceedingly funky to it, I think it should be
pretty easy to boot other OSes with it.

There is no IA64 apple hardware and likely never will be [Itanium].
I think you may have thought I was talking about x86-64 or AMD64/EM64T.
EFI was originally deployed on IA64 years ago and FreeBSD has
supported it at at least some point. Also my fellow L4 developers
have used the FreeBSD EFI-enabled bootloader to load L4 programs.
That's all I was referring to, I didn't mean to imply anyone has run
FreeBSD on Apple intel hardware.
