I think it is wrong. lynxfb_ops_imageblit() is the imageblit callback
if 2D acceleration is enabled. but cfb_imageblit() is the default imageblit
function that the framebuffer layer is providing for drivers which do not
have 2D acceleration. You will notice the default is mentioned as
cfb_imageblit() when we were defining lynxfb_ops. So we should not fall
back again to the default function even if 2D acceleration is on.

Teddy: any comments about what should be the proper fix for this?
