Yes, I remember that patch, too. I think it was this one: 
http://article.gmane.org/gmane.linux.drivers.madwifi.devel/235

IMO it would be nice to have something along these lines. It would even 
be better if it was possible to see the frames in this monitor interface 
that are generated locally to be sent, including their 802.11 header (if 
that's possible)

IIRC someone was working on a facility to inject raw 802.11 frames. I'm 
not sure who it was (/me is getting old), and don't know what state this 
effort is in.
