There is unofficial support, though! Bumblebee was fairly easy for me to set up, and works quite well (again, for me): http://bumblebee-project.org

Yes, Bumblebee is really cool.

My main problem with the Optimus configuration on Linux was overheating: as the discrete card (nVidia) was always on, even if the system wasn't using it, the computer was hotter. Without workload, the normal temperature on Linux was around 53ºC, while on Windows was 42ºC. It felt warmer on the keyboard too.

I had some problems trying to get Bumblebee to work on Fedora (at least the bbswitch worked, so the discrete nVidia card could be turned off, and then the computer wouldn't overheat on Linux). On Ubuntu though, the setup was really smooth [1]: just adding a PPA and then installing a package and everything was working :D

However, while Bumblebee is really cool, it still can't do what the official nVidia and Intel drivers do on Windows. You can run programs in the discrete card with Bumblebee, but you have to use a special command for that (optirun), the cards won't be switched on-the-fly depending on how much processing power is needed, which is the case with the official drivers on Windows. There supposedly is some progress in that regard though [2], in a project called Prime (awesome pun indeed)
