Always set the LVDS panel to its native mode, except for the 'display' part.

Browse Source 
This allows to use lower resolution screen modes with black border.

Added a set of TODOs :
 * The smaller scren is not centered, but aligned top-left
 * The base resolution used is the one reported from edid 1.1, because I'm still not sure how to parse EDID 1.2. This resolution is too small on my laptop, but it works.

Also added two ways of setting 8-to-6 dithering for 18-bit LVDS panel. No visible result for me, unfortunately.
