EFI Boot on MacPro

I've been following the steps outlined here: http://grub.enbug.org/TestingOnEFI

And so far, have been unable to successfully boot into the machine.

This is on an Intel Mac Pro. I'm trying to do it *without* rEFIt.

I've compiled grub2 on a linux machine and copied it to a HFS+ partition. As well as the vfat GPT partition.

I then booted into OS X and blessed it, tried both the HFS+ and the vfat partition.

When holding down the alt key during boot, it does not show up in the menu.

However, when I use the refit boot CD, it detects that I have grub.efi on the HFS partition.
If I select that partition for booting, it errors out, and I get the message:

"Error: Unsupported while loading grub.efi"

So, refit *knows* that the efi is there, how do I get the Mac itself to understand that?
