Hi,

The new ""Santa Rosa" generation of macbook is 64-bit. Although I
double that it's the problem. If the firmware doesn't match, you can't
load grub2 at all.

Oh btw, you shouldn't load 64-bit linux kernel in 32-bit firmware, and
vice verse.

Your problem could be caused by 2.6.27. I only test 2.6.26, perhaps
you can try that and see how it goes.
