Try the attached patch, this is basically the code from stable/6
ported to head and stable/7. I did only some basic tests but monitor
mode seems to work and it is still possible to use the card in STA
mode.

I'm not sure why that got lost, but there must be a reason I'm not
seeing right now. If someone has more knowledge about that, please
let me know, otherwise I intend to commit it this weekend.
