The last three are included in the GENERIC kernel.

The bwi and bwn drivers need firmware, which is provided by the 
net/bwi-firmware-kmod and net/bwn-firmware-kmod ports.  So install 
whichever is appropriate.  I think the driver tries to load the right
firmware automatically, but haven't tried a Broadcom in a while, and it 
might still be necessary to load the firmware module in
