HP T5530 CE Device - Changing VNC passwords

What is the easiest way to do this using Altiris. In Wyse Device Manager we extract the registry from the CE5 device and strip down only the keys we want and then distribute that back out to the rest of the CE population. But we are now buying HP termials and are going to Altiris. Would you do this in the same fashion as WDM? I see Altiris is pulling the whole image but what about just a reg extraction so we can repackage the reg files back into a distributable package.

Thanks,
