Works for me in 3.9-rc6.

As stated above, you cannot use grub to load the firmware as the information is
only accessible before you exit the boot services in EFI.  The kernel must be
booted using EFI stub booting (that's where the code for getting the bios image
is).  I use rEFInd as this now automaigcally passes the initramfs location to
the kernel.
