Well, I would think there are a lot more people who are interested
in this subject than are subscribed on dri-devel. dri-devel really
has a different scope.

The 'driver' must do mode validation using data supplied by either the 
display itself or the application (you need the second as some display 
devices may  not support sending this data or the data sent is bogus).

Broken video modes usually result from:
1. broken drivers
2. bogus user level configuration/override
