Fair point.

By default the existing modes includes only the VESA standard modes,
although I would expect drivers for TV-like hardware to override the
mode list to get the supportable CEA-851 standards instead.

I confess I'm having a great deal of difficulty trying to think of any
way to update the mode list while sticking to one file, one value.
