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. later, Peter.
