You can safely compile a kernel without nouveau, your Nvidia 
card will not be used at all since neither Linux nor the 
proprietary nvidia driver does support optimus at this time
(and frankly, I won't buy any further machines with opticrap).
So having nouveau compiled and loaded seems like a waste of ressources
in this case.

For me it's important to have nouveau working, because I try/use
Bumblebee and optirun:
