On the basis of all that, jockey is lying :) If you run nvidia-settings it will tell you the version of the driver in use. If you're not running the nvidia driver, nvidia-settings won't start, or will throw an error. I'd trust that over anything jockey says.

The final thing to convince yourself it's working is to do 'lspci -k'. This will tell you the kernel module in use for all your hardware. Mine looks like this:

01:00.0 VGA compatible controller: NVIDIA Corporation GT216 [GeForce GT 330M] (rev a2)
        Subsystem: Samsung Electronics Co Ltd Device c06a                                                                                                                                                      
        Kernel driver in use: nvidia                                                                                                                                                                           
        Kernel modules: nvidia_current, nouveau, nvidiafb                                                                                                                                                      

If it says nvidia is the kernel driver in use, then it is all working. You can also look in /var/log/Xorg.0.log, which will tell you (in amongst a whole load of stuff) which xorg driver is being loaded.
