6 Currently all frame buffer device drivers have their own video mode databases,
9   - one routine to probe for video modes, which can be used by all frame buffer
11   - one generic video mode database with a fair amount of standard videomodes
13   - the possibility to supply your own mode database for graphics hardware that
14     needs non-standard modes, like amifb and Mac frame buffer drivers (which
17 When a frame buffer device receives a video= option it doesn't know, it should
18 consider that to be a video mode option. If no frame buffer device is specified

102 	  example:  .48M3-R - 800x600 with reduced blanking
106       - aspect ratio can only be one of the above values
