I have a
0f:00.0 Network controller: Broadcom Corporation BCM4328 802.11a/b/g/n (rev 01)
it works with the b43 driver.
I am not sure what driver works for your rev 03 card.
try first removing the wl driver "removepkg broadcom-wl"
then run "depmod -aq"
check for wireless listed with "iwconfig"
if it is not working post back the results from "dmesg|grep b43"
