That should be close enough to my system, thus I cannot duplicate your problem. 
I have no idea what the difficulty might be. There should not be a major 
difference between my BCM4306 and your BCM4318 at this level.

I do not see any way to get the firmware onto the live system during booting.

If you copy any existing firmware files in /lib/firmware/b43/ on your working 
system, either from a USB stick, or from mounting a hard drive partition, could 
you then load b43? If not, perhaps we can get some better diagnostics from a 
running kernel.
