When I was setting up FreeBSD (9/amd64) to run on a MacBook Air, I used (from
within Terminal while booted into an OS X boot image):
sudo bless --device /dev/disk0s2 --setBoot --legacy
(s2 was the FreeBSD boot slice.)
My notes also claim that the drive needed to have MBR boot code installed first
(e.g., via fdisk -B ada0 or the gpart equivalent) in order for the blessing to
work. This was about a year ago (December 2011), on whatever
hardware/firmware/OS X were current at the time.
