Is what you have so far available anywhere?

I've been putting off learning more about drivers for some time, and have a
macbook 3,1 that I want to install FreeBSD on. I can probably kill two birds
with one stone.

I also have some older hardware with a broadcom nic of some kind (uses the
b43 driver on linux) that I can fiddle with.
