a.) Mac Mini's EFI implementation can use either MBR or GPT schemes for booting.
b.) If this is a dual boot situation, Mac OS X is EFI only, effectively requires GPT and an EFI System partition. Your particular Linux distribution support of Apple's unique EFI, which is not UEFI, determines whether you will boot Linux or Windows or whatever you're booting, either in EFI mode, or CSM (BIOS emulation) mode. c.) If CSM is required for the foreign OS, and this particular Mac mini, then GRUB2 EFI is inapplicable. You'd use GRUB2. And it necessarily means the nasty situation of hybrid MBR (disk appears to be MBR to the foreign OS, and appears to be GPT to Mac OS). d.) The only distributions I know that reliably support EFI booting some Mac models is Fedora 17 and Ubuntu 12. But it's hit or miss on which models will work and which ones won't.
