PhysX was a CPU driven Physics engine long before they put in the PPU acceleration, and later GPU support (was called Novodex before they changed the name), and it has a software implementation as any other physics middleware.
it is available on Win, Linux, 360, Wii and PS3 platforms, but the CUDA based Hardware acceleration is obviously not supported where there is no supporting hardware, IE on the consoles.
