I have a MacBook 5,2 and have been booting in EFI mode with rEFIt, a manually compiled grub.efi and the following grub.cfg:
set debug=video set timeout=10 insmod efi_gop menuentry "Linux (no agp, force acpi)" { root=(hd0,3) fakebios linux /vmlinuz root=/dev/sda3 video=efifb agp=off acpi=force initrd /initrd.img } Have you tried an insmod efi_gop line?
