What drivers are you looking for?
If you have the latest version of Ubuntu, the drivers should be included.
If you already tried Ubuntu and are having problems, please be specific.
If you have not installed it yet and want to see if your hardware works, what about trying the Ubuntu Live CD first? This way you see what hardware is supported and what issues (if any) that you may have.
Do you plan on keeping Windows XP on the system and dual booting Ubuntu?
