Issue 311: Enable dual framebuffers so that we can operate LCD and TVout in parallel

Reported by Nikolaus Schaller, Dec 17, 2011

The problem is that the LCD is 640x480 while the TV is approx. 
500x700.

This requires two independent framebuffers which could be configured 
to be drivern by two different screens of the X-Server.

Some hints:

With omapdrm driver we still have a single framebuffer but it is 
shared and xrandr can be used to control which part is displayed on 
LCD and which on TV.
So we can define them to show the same or to show different parts of 
the full screen.
So we have a solution since 4.3-rc5.
