The exact same message happens on F16 with GPT disks using the customize installation type, if you forget to create a BIOS Boot partition. 

I don't think GRUB2 devs mean for BIOS Boot to be required per se, but I think it's a good enough idea for a distribution to require it, because on GPT disks there's no obvious safe place for core.img to go, except in its own defined partition. grub2-install specifically looks for the BIOS Boot partition type GUID, and it only needs to be 1MB (which is also consistent with maintaining alignment for 512e and 4Kn disks).
