    It only worked by accident without DRM support, since you were using the
    ATI codepath in the firmware rather than the Intel one. That bug's been
    fixed, so now you're following the Intel codepath - unfortunately
    there's no way to do that without kernel-level graphics support, which
    means DRM.
