If this helps: I switched from grub-pc to grub-efi on my oldish Mac mini Core 2 Duo (i945 chipset) and the hard disk used AHCI after this. Suspend also works fine. So I would guess that the AHCI/PIIX difference is caused by booting with EFI/legacy DOS bootblock, and the latter is just done for Windows compatibility.
