Call drm_client_setup() to run the kernel's default client setup for DRM. Set fbdev_probe in struct drm_driver, so that the client setup can start the common fbdev client. The dcss driver specifies a preferred color mode of 32. As this is the default if no format has been given, leave it out entirely.
