Good things for sure. My biggest concern is that we have conflicting
requirements upon the mode as setup in crtcinfo that are not being
detected. The task of mode-valid is to find a compromise mode that works
for all attached connectors, and more importantly make sure we reject
combinations of connectors that would result in no compatible modes
(above and beyond the combination of encoders that are illegal).
And most of that concern is due to the fact that the modesetting code
seems to have evolved ad-hoc with very few sanity checks and no
