The link I posted for the graphics specifically says:
I downloaded the official drivers from Intel. As I understand it, Aero won't run on anything below a 3.0 WEI....The Intel® 945G & 945GM Express Chipsets will be the first Intel products to support the Windows Vista Aero user interface using WDDM drivers.
