Problems with wifi and macbook

[FW]

I have successfully installed freebsd on my macbook (yay!), but I
can't figure out how to make the wifi work.  Wired networking works
great.

I am following the directions here :
http://www.freebsd.org/doc/en/books/handbook/network-wireless.html,
but I have only got up to section 31.3.3.1, since I can't get past the
scanning part.

My ifconfig output is attached (can't figure out cutting and pasting
in icewm with the single mouse thing).  When I try run ifconfig ath0
scan, I get "ifconfig: unable to get scan results".  My loader.conf is
attached to -- I presume that the kernels are loadd, but I can't
figure out how to check.  I DO see ath0 in the dmesg.

Any help is appreciated!
