I am using the b43 drivers, all seems fine, the B43 modules is running along with mac80211, no problem there. The problem lies with the firmware. I read that the updated b43 drivers only work on my card with firmware revision 4; i currently have revision 3.
I will add that this card ran perfectly until the drivers were updated.
I have tried but cannot find a resource for the proprietary drivers. yes I have Googled, believe me i have looked. Does anyone else use this family of cards? Where did you download the proprietary drivers from?
