in the oneiric kernel doesn't support new tx header on b43 and 5.100.138
firmware requires that feature
anyway lastest old tx supported firmware source can download here but requires
b43-fwcutter-0.15 for extraction

** Description changed:
I have a broadcom 4312 chip that requires firmware to be loaded in order for
the wireless card to work. Under regular Ubuntu with Unity, I opt out of using
the b43 driver and use the restricted Broadcom STA wireless driver wl provided
by the Additional Drivers
