In May/June 2007 I failed at using Grub2 cvs - efi on my new MacBook 
too, with the same issue.  But I'm using Grub2 with legacy boot sequence 
to boot... because it understands GPT :)  and that works except the 
keyboard usually doesn't work during boot because of Apple's buggy bios.

I'm not sure if chainloading would work due to grub2 not understanding 
HFS+ ?  I tried putting grub2-efi and a linux kernel image on a 
FAT16/vfat partition.

Anyway I can probably help test anything if needed.
