I understand that the foss driver doesn't support crossfire at this time, but I'm guessing I can run accelerated graphics (aka, games) on a discrete graphics card, even though I have a integrated gpu as well, correct?

I just can't utilize both of them at the same time?

Does anyone currently successfully run a system with such a setup? :)

I'm a Nvidia user here so ignore what I say if someone more knowledgeable comes along.

You can defiantly set up your system to use the discrete card instead of integrated. You might be able to implement switching between them for power saving purposes, but you cannot use them both at the same time in a way that gives you more performance (that's what crossfire is).

Letharion,

You cannot use both graptics chips in crossfice mode so that they both work on rendering the same frame at the same time.
You can still use both graphic chips at the same time if you want to connect lots of displays.
