Nexus One: trackball power button?

Question

Android

Before the advent of Gingerbread, it was possible to redefine the power button using the program (trackball was used). There is an option to use the sound buttons, but it does not suit.
Perhaps someone met a sane firmware? Or is there another way to solve?

Answer 1

CyanogenMod - sane firmware

Answer 2

Phone power button or screen power button? The so-called wake up.
