MacBookAir i7 OSX Lion Performance Woes

With the new beta 5 the second display on my MB Air does not work any longer. It just stays black. Attached is one Apple cinema by the display adapter and another over USB. With the beta 4 it works, but slow.

I already tried to uninstall and re-install the drivers but without any effect. only re-installing Beta 4 brings up the screen again.
