Because nvidia's driver licensing terms require you not to be using the consumer stuff in a datacenter.

What if you're running Linux with the nouveau driver?

It's irrelevant. You need the CUDA SDK and the CuDNN SDK both of which have license agreements.

Edit: You may also need the official Nvidia driver. I have never run anything with the OSS drivers.
