I doubt there is a reference platform, but if there is one it's really with intel graphics. Only this, from a laptop point of view, has the kind of support that is needed from a thermals point of view. AMD is apparently nearly there with new power managment code, so this may change in the future. Obviously if you want to use binary drivers, you can, but one would hardly call that reference, inofficial or not.
