b43 does not work with 4353 in Macbook Pro 6,2

[Jeroen van der Vegt]

Hi,


When I load the B43 driver on my Macbook Pro 6,2 ('rmmod wl; modprobe
b43') all modules are loaded fine but no network device appears. I'm
running Ubuntu 12.04 (3.2.0-32).
On this list I read that recompiling 'wireless-compat' with
B43_BCMA_EXTRA='y' should help
(http://lists.infradead.org/pipermail/b43-dev/2012-March/002457.html).
I don't feel like having to compile my own kernel as I used to , so I
hoped installing 'linux-backports-modules-cw-3.3-precise-generic'
would help. This didn't change much however (features L and S appeared
in dmesg) for the b43 driver but broke the wl driver.

It seems the option was deliberately disabled in the Ubuntu kernel:

:(


Cheers,

Jeroen.
