Well, looking at the commit history of both the siba source and the
port containing the firmware binaries, I'd say the driver is in
maintenance mode since March 2010. Which nicely lines up with the five
year old chips, unfortunately. No idea if it is indeed as simple as
adding a few PCI-IDs and the binaries but if you have such a device,
maybe you could try it?

The page also claims that the operation of b43 is limited to 11g? Is
this correct?
