Why are you blacklisting b43?

The only other things I see are as follows:

This line from the dmesg output looks strange.
[   53.905515] b43-phy0 ERROR: PHY init: Channel switch to default failed

The rev ff in the lspci line is also strange. My BCM4312 shows rev 01.

02:00.0 Network controller [0280]: Broadcom Limited BCM4312 802.11b/g LP-PHY 
[14e4:4315] (rev ff)

My BCM4312 device is in a 32-bit netbook that I seldom run. It will take a 
couple of days to get its kernel updated to the current version so that I can 
test the latest b43 code. I will report those results ASAP.
