The Windump method is pretty sweet when you set it up right. The only 
drawback is that you can't turn off the Nvidia GPU without freezing up 
your system.

On of the side projects for the Bumblebee team right now is running 
Windump through a Bumblebee X server. By doing this, we can disable the 
card when we're not using it.
