I think your firmware suggestion is probably the right one. I've owned a 
succession of laptops/netbooks all with some variant of the broadcom 
43xx chipset.

There are two versions of the firmware. The simplest way to achieve 
liftoff is to connect to the internet via a wire just one time and 
install the firmware-b43-installer the package, which downloads the 
firmware and installs it. (If it is, as the log entry would suggest, a 
"lp-phy" version of the chipset, it will tell you to install 
firmware-b43-lp-phy-installer - I think that's the name, which does the 
trick for that chipset).

After which rmmod b43 followed by modprobe b43 will reload the kernel 
module which will load the firmware and everything should be OK.

Worked a treat for me a couple of weeks ago on my HP netbook, which is 
running the Mint Debian Edition.
