Turning off second nvidia card in hybrid SLI setup

I've just got a Dell Studio XPS 13 that has an Nvidia Geforce 210M, which has hybrid SLI (with an integrated 9400M card).

The nvidia driver only uses the integrated card and I know that the nvidia doesn't support hot-switching to the 210M in its linux driver. But is there a way of turning off the 210M to save power (since its not being used anyway)?

Here is the output of my lspci:

Code:
% lspci | grep VGA
02:00.0 VGA compatible controller: nVidia Corporation Device 0a74 (rev a2)
03:00.0 VGA compatible controller: nVidia Corporation GeForce 9400M G (rev b1)
