[ Looks like people are too busy explaining why you shouldn't use
  grub-efi to actually answer your question. ]

The problem may simply be that the `intel' Xorg driver relies on the
BIOS of your video card, which is usually initialized by the legacy BIOS
but is not initialized by the normal EFI boot.

Checkout http://grub.enbug.org/TestingOnMacbook where they provide some
steps that may be helpful to fix your problem (e.g. how to tell EFI to
initialize the video BIOS).
