We already ship a similar script based on the debian package for
b43-fwcutter (with some adaptations for our rootfs layout), that would
download the drivers, extract and install firmware for the user, so we
could just ship the files as well. What I was trying to avoid is
shipping those files, and that's where extracting from the Windows
drivers would come in handy.
