Although the nvidia card is still powered up and sucking battery life. I tried messing around with some utilities (Bumblebee) that are meant to control power or selection of graphics card, but all I achieved was hard lock-ups. (That was on a 3.10 kernel, mostly default X from Ubuntu 13.04, and an updated nvidia driver. So things might be better with later versions of X components. Allegedly it does work for some people.)
