Release: grub2-efi-2.00-23.fc19.x86_64

To reproduce:
1. Updated to grub2-efi-2.00-23.fc19.x86_64
2. Clear NVRAM of all boot entries.
3. mount /dev/sda1 /boot/efi to mount the FAT32 ESP (instead of the default
Fedora hfs+ ESP)
4. grub2-install
5. grub2-mkconfig -o /boot/grub2/grub.cfg
6. reboot
7. At grub menu, choose OS X 64bit entry.

Actual results:
xnu kernel panics

Expected results:
Boots normally.

chainloading the Apple bootloader allows xnu to boot normally without kp, as
does holding down the option key and choosing the firmware listed OS X volume
boot option. So it's definitely some issue with the xnu module.

Also, this doesn't work with any xnu 12.x or 11.x kernel (which goes back 1
and 2 years respectively). I'm not sure which version of xnu it does work
