I guess you tried downloading the new drivers from ATI's website, but did you try uninstalling the old drivers first?

I've got the Radeon ATI 9800 Pro (not an AIW)(All In Wonder)) and installed the new Catalyst Driver Suite Software on their website here: http://mirror.ati.com/support/driver.html

Device manager definiately says: "Radeon 9800 Pro" but then again it may be different with the All in Wonder.
