Bruce, when I posted, I did not remove the stuff that may not be needed 
just for Alan's card. This is the way his Fedora distro runs. I may not 
have been clear, but only the left column is relevant, and which drivers 
he needed to have configured to get his card working.

Thanks for pointing out the 80211 stuff. Another rust spot for me.

I have the same card and have not yet discovered a "firmware blob." I 
did, however, encounter one for my wireless card. But that's for later 
if he has the same setup that I do.
