But now I think it's starting to make sense. Chameleon's stage2

AFAIK Chameleon's boot is based on Apple's older, pre-EFI boot loader
(http://opensource.apple.com/source/boot/boot-132/) that performs similar
functions but does not require EFI and works on BIOS based machines. It is
updated to work with recent EFI-only releases, also provides some EFI
stuff that's needed by OS X (fake_efi) and has some means of patching up
non-Apple hardware to work with OS X. To make sure it's not trying to
patch anything try to remove all modules (may need to recompile to get rid
of built-in modules) and make sure all *Enabler options are disabled.
Alex was talking about (i.e., eventually getting TianoCore to pick
up and run "boot.efi" as left behind by the vanilla OS X installer).
I've also found this:
http://sourceforge.net/apps/mediawiki/tianocore/index.php?title=OvmfPkg
which might be what we need for using Apple's boot.efi but I don't know
how ready is it and if it works with OS X.
