True, and I was expecting problems like this when I decided to keep supporting
vanilla kernels. But at the moment i am just considering what the best options
for rt2x00 would be.

I have seen that package, James is as far with backwards compatibility as
we are in rt2x00. But we are apparently hitting against the same problem.
But there is some progress I believe, Robin seems to have managed to
compile cfg80211 now against a 2.6.20 kernel. So we probably need some
research now to add older kernels to the supported list. ;)
