--- Comment #11 from Daniel Vetter <daniel at ffwll.ch> ---
It's somewhat expected - we do the automagic broadcast mode detection by
comparing the passed-in mode to the exact mode from the hdmi spec. Now
unfortunately no one has yet bothered to teach the drm core that some hdmi/cea
modes also work with 1000/1001 the refresh rate. So we neither expose those in
the mode lists the kernel generates, no do we correctly set hdmi infoframe
parameters and decide about the broadcast mode correctly ...
