Can a PowerBook or MacBook be configured to automatically wake when power is connected?

Question

I'm looking to turn an old Mac laptop into a "car-puter". However, I don't want to drain the battery on either the laptop or the car. Is there a way to configure it so that the computer automatically wakes up when plugged into power? (I know that it can be woken via ethernet, but I don't know how I can turn that to my advantage.)

My specific use case is a late-model PowerBook G4 running 10.5, but I'm also curious about whether this can be done with other models or OS versions. Thanks!
