In the 1. Select a product family, choose Graphics
In the 2. Select a product line, choose Desktop graphics drivers
In the 3.Select a product name, is where you might get lucky. If you choose the "4th Generation... '4400" entry, you'll only get Windows 7 and 8 drivers. If you choose the "3rd Generation... 4000" entry, you'll find some XP drivers.
