  No - the standard allows both GPT and MBR, and the EDK-based bhyve 
UEFI will handle that (as I think you saw when you manually created the 
FAT system partition).

  However, GPT is really the preferred partitioning scheme for EFI, and 
it's not surprising that OpenBSD isn't creating the system partition 
when MBR is selected.
