For the heck of it, I'm attaching a patch that takes the suboptimal, but
functional approach. This looks for 47[01][0-9a-f] chips. This should
include some of the earlier 47xx chips which share the same firmware.
This is a pretty broad brush, but I know there are quite a few other
types of devices out there.
I also looked through https://wireless.wiki.kernel.org/en/users/Drivers/b43
and added everything that was there. Some of those need kernel 3.18,
but I imagine the next version of firmware-b43-installer will be out near
the next Debian release when I imagine that will be standard. I actually
prefer the script's new default of simply always installing the firmware
and not bothering to check for presence of the hardware.
While I was at it, the attached patches also do some cleanup on the
script. The big case statement is using ranges to match multiple chips,
since that blob is getting too big otherwise. Also moved the detection
of the BCM4306/3 chips inside the case statement (should be faster).
One major remaining concern with the postinst script. What about systems
with multiple Broadcom 802.11 chips installed? If I have a very recent
system, I might plug in an old legacy chip card for initial installation
when the firmware/driver for a newer chip isn't readily available. In
this case, the script will fail since it has a legacy chip, when it
should succeed because it also has a newer chip...
Got to revisions of the patch, the difference is rev1 is more aggressive
about combining chip id ranges together. I don't know which you prefer.
