I've merged a patch from Chris to detect additional sdvo TV outputs:

commit a0b1c7a5197293d6206b245b45edc3f508aadab6
Author: Chris Wilson <chris@...is-wilson.co.uk>
Date:   Fri Sep 30 22:56:41 2011 +0100

    drm/i915/sdvo: Include YRPB as an additional TV output type

So that explains that hopefully.
