Wait .. I see I used the wrong firmware version for my kernel.

Hi Mike,
You need to grab this file:
http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2
Extract and then do
[]# b43-fwcutter
-w /lib/firmware/ /path/to/broadcom-wl-4.80.53.0/kmod/wl_apsta.o
This is what brought my BCM4306 to life.
HTH,
Jeff
