Re: /stand/i386/boot0/boot0.S and other boot files under i386

boot0.S is only for MBR. And really only loading the boot blocks from the
start of a partition.
pmbr.S is for GPT. It loads the freebsd-boot partition for the next stage.

I'm biased against breaking compatibility generally, but might make an
exception for a specific thing.

What were you going to break? A lot depends on that...
