Is it possible to have a driver that is compatible with WDDM, on a different video card?

I have a computer, and just upgraded it to windows 7 recently. The aero effect wasn't working, and I found that I needed a driver that is compatible with WDDM. I asked other people, and they say my video card is too old to do the aero effect. Since it's lower than 945GML, I can't run aero. But is there a way to get aero, or there is no way.|||i will answer u later...
