Well, I'm no expert in Silicon Motion hardware, but a -logverbose 4 log (with an SM722 as secondary) might provide a clue. There are also a couple of shots in the dark you can try: 1) Add Option NoUseBIOS to SM722 secondary screens; 2) Change SMI_PreInit() to not get rid of pSmi-pInt10 before returning; 3) Uncomment SMI_PreInit()'s calls to xf86SetOperatingState(). Thanks, and good luck. Anything more on this?
