you can install XP, let it install its default drivers, then go to the manufactures web site and download the correct drivers for your OS.
This will also let you get the most up to date drivers.
If your going to move from Vista... I'd move up to Win7, not down to Vista.
You can get the upgrade version for pretty cheap, and it'll last longer. XP's end of life is April 8, 2014. http://windows.microsoft.com/en-us/windows/products/lifecycle
