AFAICT Option "Noaccel" completely disables hardware acceleration.
Together with Option "shadow_fb", it should operate more or less the
same way the fbdev driver does. If you're still seeing a difference in
performance between the two drivers, having a more detailed description
of the difference and seeing the full Xorg log files corresponding to
both cases would be interesting.
