BTW, it's really easy to test efi image with the latest refit. Just
install refit 0.11 in OS X, and it would be used as the default boot
manager. Then, copy an efi image to / or /efi/xxxx/ of any
fat/ext2/ext3/hfs+/reiserfs partition (remember to install the fs
module, though), and it show up automatically in the boot menu.

You can verify it with refit 0.9 which use ia32 image. Download the
binary package, extract refit.efi to the root directory, and it should
be in the menu. When you choose it, it would say unsupported image.

(refit 0.9 worked for me in OSX, I don't remember whether I'm using 0.9 or 0.10 right now)

But I'm sure I was building an ia32 grub2, and refit quite happily loaded that image -- it was just was in grub2 "rescue mode" for that old efi grub2.

And I meant that if I had to compile anything grub2, I wasn't sure if a 32bit Linux could make a 64bit grub efi image.. but if you can make the image, then no problem at all!
