Utility to undervolt, without taking over powermanagement

[TJMacGyver]

Can I somehow undervolt the CPU and still use the builting powermanagement (PM) in Vista Premium?

I have tried RMclock, But I actually can't figure out entirely how it works, (it's a very confusing GUI, I think) I got it to change the "VID's" but only if activated a powerprofile.
but then the Vista built-in PM doesn't have any effect, I think.

So what I wan't is to somehow ONLY change the Volt-settings. And NOT affect the built-in PM.

Are you trying to get more battery life, less noise or both? It's an interesting problem...
