This doesn't do any accelerated graphics. It remains to be seen if NV are just trying to make life smoother for the proprietary parts of driver stack on Android by getting the the HW initialization etc into upstream Linux, or if they are aiming to actually do an open 3D driver. They haven't announced any plans about the latter.
