Hi,
Thanks for the idea, here fat grub.efi tested ok on imac8,1 (64) and
MacBook2,1 (32), using working grub32.efi and grub64.efi with their
preloaded modules.
./fatglue.py grub2202f.efi grub2202-32.efi grub2202-64.efi
compile and fatglue were all done in OSX10.5.6.
Debian sid 2.6.29.1-amd64 boots for me on imac8,1 using
menuentry "sid amd64 fbdev sda9" {
fakebios
root=hd0,9
linux /vmlinuz root=/dev/sda9 video=efifb noefi
initrd /initrd.img
}

I have been using the svn trunk over the last few days with some
success compiling 32 and 64 bit EFI grub and creating a dual
architecture grub.efi from the results that seems to work on hard
disk on newer and older Apple Intel Macs. I use the fatglue.py
python script from refit to make the fat grub.efi. Not sure if
anyone else is doing anything similar...
I have observed that fat modules don't work - need to use
grub-mkimage to insert all the required modules.
Another interesting observation (not really grub but maybe worth
comment) is that using a Linux 2.6.29.2 kernel and initrd on the
newer macs in efi mode boot (uses framebuffer console) works up
until the insertion of modules. It appears that some modules do
insert and other don't. The same kernel and initrd booted in
"legacy mode" (after a call to fakebios) boots fine.
Finally, the reboot call from linux on the iMac 9,1 hangs -
possibly an issue with fakebios??? If the output of grub-dumpbios
is any use let me know...
Models tested (all intel)
macmini
iMac 4,1 requires ia32 or "fat" grub.efi
iMac 8,1 requires x86_64 or "fat" grub.efi
iMac 9,1 requires x86_64 or "fat" grub.efi
