fc4 + Broadcom BCM43xx wireless support?

[Robert Story]

I saw a message on wireless support via a rawhide kernel on (what I assume to
be) stock fc4.
[http://www.redhat.com/archives/fedora-test-list/2005-December/msg00820.html]

However, that is a 2.6.14 kernel. Is there a patch, instead of having to grab
a binary? Does it apply against newer rawhide kernels? Any chance of a
patch against a fc4 kernel? Anyone running a rawhide kernel on an otherwise
stock fc4 machine?
