Har ikke dette heelt på G, men du vil vel kun kunne benytte en av GPU'ene - og kan ikke velge hvilken du vil sette opp for.
own a Thinkpad T410 with Intel i7 processor and Switchable Graphic Card: NVIDIA Quadro NVS 3100 and Intel Integrated Graphics Card. In the following I describe how I've been using Gentoo Intel GMA HD (Arrandale) and the NVIDIA graphics card to run with. That is now possible only through a reboot, and the switcher of the graphics card in the bios. Fortunately, can be switched on in the BIOS ThinkPad T410 between the two graphics cards so that each card individually in the system is (many other laptops do not offer the Bioseinstellung). The NVIDIA Optimus mode only works with Intel graphics card that NVIDIA is for the system visible, it is not me but managed to activate the card (via vgaswitcheroo).

Switching graphic cards
This laptop sports two gpus. The Intel GMA HD (Core ix integrated) and the Nvidia Geforce GT 335M, with the ability to swith granted by Nvidia Optimus technology.
However, the official proprietary nvidia drivers for linux don't support Nvidia Optimus yet. Some experimental work is being done with Nouveau and hybrid graphics [2]
Kernel 2.6.34 includes vgaswitcheroo which, in theory, makes it possible to switch between graphic cards. Despite working with Intel/Ati[3], it is still not working with Intel/Nvidia. That should change in the near future[4] [5].
