I would like the ATI graphics to default to a known working state when a user logs into Windows XP, regardless of whether that user has tried to change the settings. How do I make that happen?
do you want to lock down the setting or simply reset it? you can reset it with group policy preferences or a login script, or (and what I would likely do) lock the resolution of the system with group policy. Nowaday unless you are on CRT the resolution should match the resolution of the monitor.
