Pairing two different cards

Hello there,
I'm having a laptop with Core i3 2350M processor and was suprised when I read on Notebookcheck.net that this processor has an intergrated Intel HD3000 graphics card inside it. At the moment I'm using AMD Radeon HD7470M 1GB dedicated graphics card and I was wondering is there any way to enable that Intel integrated GPU to work along with the AMD card? I understand that I can't pair them with Crossfire because one is Intel one AMD but I think I read somewhere that you can run 2 different gpus without cf or sli but they will work different or something like that (one will just take a load off from another)...That's why I'm here asking you can this be done or I'm just hallucinating...

I don't think it can be done. But I think I heard somewhere that the integrated GPU inside the CPU helps with video rendering, but I could very well be wrong about that.
