Surprisingly, the way I have gotten it to work is to use a good,
old-fashioned BSD-style disklabel. I just installed FreeBSD 10-RC1 on a
Mac Mini, but it was the oldest possible Intel version (a 1,1).
If you install 9.2 the way you would install 8--use an MBR partition
with BSD disklabel on slice 1, you should get it to boot.
I am not close to the machine right now, and it's powered off, but I can
fire it up and send you the partition/label parameters.
Again, this is a very old 1,1 (still, it's an EFI system, but it's only
32-bit), but the same scheme might work on your system as well.
