I think you have the right idea. As you pointed out, there's a lot of
duplication between lcd code and video code which should be eliminated,
and this is a step in that direction.

Hannes Petermaier is currently also working on lcd console functionality
(Introduce lcd_console rotation), and I recommend that you sync with his
patches (V2 has just been posted).
