Hmm, can I make use of GPT without having boot support? Perhaps you have a 
link handy which illustrates the GPT on disk and the BIOS interactivity. Is 
it possible to have both, MBR and GPT? I can't imagine.
My particular problem is that I want to have every jail in it's own label, but 
then I have to slice my disk (array), because I have roundabout 20 jails, 
which makes it impossible to rearrange label-sizes.
