Any of ATi's cards with a model number 8500 or higher have some level of vertex shader and pixel shader support (also SiS's recent cards have partial support for them.. and I believe Matrox's last card has support too...). The format is different than nVidia's, and I'm unaware as to whether or not XBox's version of DirectX has a high level shader language similar to the one present in DX9 (I think?).. if so then it'll probably be possible to emulate them in DX9, and then the driver's shader compiler will take care of the rest. If shader programs are written in ASM on XBox games then that's another story; it'll be hard to support them with any decent speed on non-nVidia cards.
