Code is in head and needs backporting.  I have no time.  Everything you 
need should be in the sys/dev/ath/ath_hal/ar5416 directory.  It might be 
possible to just apply the commit from HEAD though there's been 
significant divergence so possibly not.  Remember it does only legacy 
mode (no 11n) and seems to have some bugs (chip locks up and gets 
reset).  Atheros only cares about  linux so fixes must come from sifting 
linux crud.
