[arch-general] grub2 efi image files

Hi, I could swear that some time back some version of archboot media gave me the choice to select grub2-efi-32-bit. Was this dropped? I've been trying to install arch only (single boot) on a EFI-32 mac. Due to not being able to convinve (bless) rEFIt without having OS X installed to not come up with a delay of >= 20seconds, I wanted to use EFI. The mac has onboard intel i915 graphics which I know to work out of the box. Would this give me any issues like the nvidia guys with using EFI? What is the exact issue I have to be careful about to not brick the firmware with EFI? I know I shouldn't use efitbootmgr on mac efi. What else is dangerous? Thanks, Carsten
