glxinfo reports that dri is enabled, but running apps that use opengl (like Google Eart, Celestia, or any opengl game) doesn't work. Running kwin composite effects works, though. System is Dell Inspiron 1525 with Intel 965GM integrated card running Ubuntu Intrepid.

Starting the programs work, but Google Earth and Celestia have severe drawing problems - the main window hides settings windows and open menus.
