Ok, so the nvidia DDX is busted. No huge surprise, too bad we can't

Oh, this is CompositeWrapper stuff. With EXA rolling into most of the
other drivers, the need for this code will be eliminated for everything
except existing nVidia drivers.

I'd like to know what changes would be required in an environment where
you had access to the driver code and avoided the composite wrapper
mess.
