Kind of the opposite: UEFI expects GPT, but also expects a particular
set of partitions. And then there's the SecureBoot situation.

Yes. There should be some sort of legacy boot. In UEFI mode,
SecureBoot can be disabled, so with the correct partition layout FreeBSD
should boot even in UEFI (untested, I do not yet have a UEFI system).
