Unfortunately, the legacy BIOS won't be able to boot from a disk like
that, at least if we don't want to violate the GPT standard.

The most trivial violation might be to put code in the formerly-boot-code
area of the PMBR.  It would probably be hard to fit code that groked
GPT in that small space, so there might have to be some assumptions made.

A larger violation (IMHO) would be to have some sort of hybrid partitioning
scheme, this would certainly break other implementations of GPT.

Perhaps we should create some sort of NetBSD Partition Table that is
similar to GPT, but can be put to more universal use.  Or I suppose
I could try to grok that insane Extended MBR system.  Whatever.
