Thanks for sharing that with us. 

Booting my MacBook2,1 with grub-efi had been on my TODO list for a while
(especially since it seems to be the only way to boot from a USB stick,
and to allow grub to see and therefore access anything else than the
internal hard-disk).

So, I finally found a bit of time to try it, and successfully booted
Debian with grub-efi installed on a USB stick (using 'fix_video' and
'fakebios' in the grub menu entry) while retaining grub-pc on the
hard-disk for now.

So far, everything seems to be working : efifb provides a nice textmode
console, and X.org using the 'intel' driver runs seemingly just as fast
as when legacy booted (judging by the output of glxgears).

However, a few questions remain for me:
- what are the actual advantages and drawbacks from booting in EFI on
  such a platform?
- where is it best to put the grub.efi EFI application? is it advised to
  have it sit on the first EFI system partition, within the EFI folder?
- if not, where?

Cheers,
