I hesitated for the same reason. Except that by filtering out all modes except for the one true mode, we prevent the user from being able to make a choice. They'll invariably make the wrong choice and file a bug, but nevertheless... ;-) I also don't think this is the way we want to approach this. The overrides required for fake LVDS headers would seem to be a superset of this functionality. -Chris -- Chris Wilson, Intel Open Source Technology Centre
