Shouldn't be there also a warning that GPT can not be used with the 
FreeBSD native bootselector? I had trouble installing FreeBSD 
9.0-CURRENT a while ago with default being GPT on my notebook and also 
wanting a Windows 7/x64 for presentations, selectable via the FreeBSD 
bootselector. This was possible with MBR, but it seems gone with GPT.
