It also changes nouveau to always register its raw interface, as all the other kms drivers do, acpi_video_backlight_support() is only intended to avoid the loading of multiple (possibly conflicting) firmware drivers, not to avoid loading raw drivers. In the mean time I've gotten feedback from a user with a laptop which needs video.use_native_backlight=1 and uses nouveau, and he has confirmed that this patch-set works as advertised, see: https://bugzilla.redhat.com/show_bug.cgi?id=1093171 Regards, Hans
