That surprises me.  Is the cg4 the reason for performance?
I would think the Xserver a more likely culprit.
Does the machine have lots of RAM?

It is fairly easy to add support for new memory-mapped display
boards.  One just needs to figure out how X expects the memory
map for the device to be laid out (for mmap access).

Getting probe right is harder.  (I still don't have the probe
quite right for some of the frame-buffer drivers...)
