Ah; I see my tree that I did the diff on was missing the 
wireless/Makefile and the ieee80211/ieee80211_module.c to create the 
patch against... sigh.  Attached is ieee80211_module.c; you have the 
change for the Makefile to include ieee80211. 

Later {hopefully today} I'll send a full patch that includes several of 
the corrections you called out in your prior patch.

Thanks,
James
