Apple's EFI implementation does not provide a way to fetch the vbios after the
OS takes over. IIRC, you need a special bootloader and kernel support for
fetching the vbios before passing control to the OS. I think Matthew Garret
had patches to support this at some point, I'm not sure what their status is.
The other option is to boot using the legacy bios interface (not EFI).
