I modded the ATI 9600 Radeon driver from ATI's site with Mobility Modder and got CCC for my ATI Mobility Radeon 9600. Just follow the Vista steps exactly on Mobility Modder's website.
Well, CCC works with my ATI Mobility Radeon 9600 on my ThinkPad T42 in Windows 7 RC1 (using Mobility Modder to mod the ATI Catalyst suite for Vista 32).
