Hi Roy,

Thanks for the info.

Dmesg above has already told you where it's looking for the firmware:

b43-phy0 ERROR: Firmware file "b43/ucode29_mimo.fw" not found

so that would be /lib/firmware/b43/ucode29_mimo.fw

A common trait emerging seems to relate to firmware failing to load, and 
I believe the new v3.5 compat-wireless branch uses a new firmware loader 
so I suspect some incompatibility somewhere along these lines. I'll try 
to look into this next week but it's difficult without hardware to test.

With the driver loaded, do you see any firmware related modules loaded? 
For example, any output from:

/sbin/lsmod | grep firmware

and can you show us:

/sbin/lsmod | grep b43

Thanks.
