You can't make proprietary driver using firmware of your choice, so
don't bother looking at MIPS drivers stored at Larry's server.

You just need to find a /complete/ (mostly closed source of course)
driver 6.20 for x86/x86_64. I don't think it was ever published on
Broadcom's site, I think it was made available to Ubuntu only under
some agreement. So keep looking at Ubuntu resources.

Also linux-wireless ML focuses on open source drivers, so you may have
more luck asking at Ubuntu community.
