Well, the EFI spec is, well, EFI-centric.  All hail our new EFI 
overlords, and all that.  Otherwise, it might have specified a 
GPT-centric BIOS boot protocol, but it didn't do so.

We can come up with another protocol, but it wouldn't be able to boot 
Redmond OSes, and $DEITY only knows how many would follow it.

The bigger issue is that the PMBR being, well, an MBR, has a 
4-paritition limit, and even two boot partitions could overflow that if 
they are noncontiguous.
