Hmm, the installer for FreeBSD/{amd64,i386} is supposed to do this 
automatically.  We used to set this in the PMBR by default for all GPT setups, 
but that isn't really correct for the GPT standard and needs to not be present 
when using EFI.  The solution was supposed to be that we would stop setting it 
in the PMBR by default and change the installer to set this bit when doing a 
non-EFI GPT install on x86.  I think the first part of that (not setting 
active by default) happened in 10, but not the second part (fix the installer 
for non-EFI GPT installs on x86).  I've cc'd some folks who've worked on 
bsdinstall who can hopefully get this fixed.
