Well the (proper! lets not get into that again... ) graphics drivers would add in support for the CUDA features of the card, no?

And how does one have a computer run without a processor? You don't happen to have a USB plug sticking out of the back of your head do you?

I for one would like to see some of our very talented folks (Luuk, Sascha, Nitro or the NECROubers) give a quick demo a try. I'm sure I'd be amazed at what they manage to do.
