They both use the same driver model so if there is a driver for XP, it will work in 2000. Obviously there are more default drivers in XP than 2000 since its newer but all you need is a driver disk or access to the Internet. If you have the latest hardware chances are no OS will come with the drivers and its usually best to download the latest drivers anyways. You can use third party or MS patches to make up for other short comings in out of the box support...
That may be the case, but after working in an enterprise IT organization for 5 years and planning an enterprise wide upgrade from 2K to XP.. my personal experience differs.
Agree to disagree?
