You're correct.  I keep forgetting just how old the codebase is.

Basically after the device has been initialzied, we need to issue an 
prism2sta_ifstate(hw, P80211ENUM_ifstate_enable) call to kick the 
hardware into a running state.

Try the attached patch.  It's completely untested but should do the 
trick -- if wlan_wext_write is enabled, that is.
