This was possible with MBR, but it seems gone with GPT. If you install onto an already MBR-formatted disk (say, you're dual-booting), it will use MBR as the default, not GPT. It only uses GPT as the default if you (a) put in a totally blank disk or (b) say you want to dedicate the disk entirely to FreeBSD. -Nathan
