A framebuffer device is usually slower than a native driver under X.

My Freerunner's UI performance definitely felt a bit faster after moving
to the native driver.

I also noticed this in my SmartQ7 after moving from the framebuffer to a
native driver.

The slowness of the graphics is better explained by the brain deadness
of the hardware.

Now... Qt from framebuffer devices is very highly optimized, so it may
be a bit faster than other Windows managers, but it also does a lot less
(like not being exactly a window manager).
