The omapfb driver is not meant to make updates automatically, except on
a few special cases (currently on initialization and when unblanking).
It's the user space's responsibility to update the screen.
The reason for this should be obvious if you think of a use case where
you have, say, all 3 overlays on the LCD, and you want to pan all of
them.
