I tried this. I'm able to start an XServer which shows up on my PC. But
when I try fbgrab to see the actual frame in the framebuffer I don't see
the same thing. I see just a static green screen (green screen is
initialized during fb driver setup).

Am I doing something wrong with my fb driver implementation?
