I don't want such heuristics in fbcon, they are just asking for trouble, I think we should redraw on non-accelerated and copy on accelerated, but then, it should be under more direct driver control. Also, fbcon keeps "losing" the accel_flags for me. One thing I don't like in the new fbcon is the way it deals with the var structure anyway. I think it should have one var per VC.
