Unless error of my part, the bcrm driver, while being released with an
ISC-like licence, do no support that chip (cf [0]). However, the b43
driver do support that chip, but is GPL...

There was an article recently on lwn.net describing the situation
where both the b43 and brcm supported the same chip, and the issue
raised that there was no point in brcm being mainlined in that
state[1]... I'm not sure what the outcome was.
