Hybrid Crossfire is pretty much Windows only and works best with similar mid to high performance cards.
"Hybrid CrossFire performance is limited to LOWEST performing card times two, if we could get 100% efficient scaling. So buying a discrete card that is more than 1.8x faster than your integrated graphics card would be overkill and a waste of money."

There was a recent update to the Lucid HYDRA 200 Multi-GPU processing technology, but that is Windows only. It allows GPUs from ATI and Nvidia to work together.
