MacOSX requires EFI64 to boot, probably because doing the bootstrap
from 32- to 64-bit mode is a bit tricky. This isn't really arbitrary,
but it is annoying, and is typical of how Apple tends to punish early
adopters. My test lab has a lot of the original generation
Intel hardware (1st generation Intel Xserves and MacPros). All these
machines run 64-bit Linux (and FreeBSD, and OpenSolaris) just fine,
but none will run MacOSX in 64-bit mode due to not having EFI64. This
irritated me greatly, especially since the hackintosh people are
booting whiteboxes into 64-bit MacOSX.
What I finally did was to use the hackintosh "pc-efi-v10" bootloader
to boot into 64-bit MacOSX on our 1st generation MacPros, using the
Linux partition's grub bootloader to launch the hackintosh bootloader.
Its all very Rube-Goldberg-ish, and it has all the disadvantages of a
hackintosh (no decent video support, etc). But for what I need
(an x8 PCIe slot in Mac running a 64-bit kernel), it works well
enough.
Why do you absolutly need to boot on 64 bit Kernel ?
Does you machine have more than 32 GB of RAM ?
