I really don't know why you guys are arguing about this.
The demo Psuedo made was running on a dual G5 Mac running a special version of windows and an ATI 420 video card.
1. The phsysics engine is Psuedo's own engine. It's not Havok or Math engine.
2. MS never said Intel had anything to do with the hardware, otherwise Intel would insist on them telling the public thier name.
3. ATi makes cards for the mac as well, so drivers is not an issue The drivers being used on Mac right now are more than likely created to be ported in the first place.

Why couldn't the demo be performed on a standard windows PC? DO you have any idea how difficult and CPU intensive pshsics like that is? Most people don't know that having stackable objects in a game is quite the phsysics feat, and what psuedo did is damn impressive.
