This helps a lot of drivers, but I have no idea what percentage
of Fedora users that represents.  Do we know what percentage that
_should_ be?  Do we have smolt data to support meeting that percentage?
I suspect that this is just a waste of memory for most desktop (as
opposed to laptop) users.

Also, as someone pointed out it is still common practice for people
to run the compat-wireless package of back-ported drivers (and the
matching mac80211 components).  This might make life more difficult
for those users.  (NOTE: these are not the typical "out of tree"
drivers -- they are in-tree, just a different, later tree.)

Finally, _if_ we build these in then we should probable build-in the
crypto modules that mac80211 requests...

This only helps two drivers, ipw2100 and ipw2200.  I don't think this
is worthwhile.

And FWIW, I ACK all the non-wireless bits! :-)
