I spoke too soon. Coincidently, I am also currently trying to get this to
work, and I'm hitting problems, albeit different ones.

I see hostapd trying to send a frame on an interface for which the initialisation
call in rt2x00 never happened. In my case, the system blows up on an uninitialised
spinlock. On a different system, things appeared to work, I could see beacons. It
may well be that your system is somewhere halfway, functionality-wise ;-)

Ivo van Doorn knows everything about the rt2x00 drivers.

I'm not sure. As far as I see it, there is a missing initialisation call.
Right now, I would point the finger of blame at mac80211 or maybe hostapd. ;-)
But I'm still trying to understand how everything works. :(
