I've been using the LP-PHY version for a few years now, and it works well
with the firmware. The firmware-installer package depends on an
extraction tool b43-fwcutter, and the docs indicate that it might be able
to do the extraction offline if the right file was available.
I may be wrong about needing the windows driver. The man page shows an
example bcmwl5.sys file to be 'cut' but seems like it only supports wl_*.o

It's all very mysterious, especially when people assume hardware should
'just work' with very little input or setup.
I can imagine a copyright line that says something like, "...you may
redistribute this software only in whole, and may not distribute only the
portion required to make the device work the way you want."
