Power button/Screen sleep re-map?

[awesomemn]

I am wondering if I can change it so the back arrow or end call button wakes up the screen from sleep mode? Any button on the face of the phone or even tapping the screen would be fine with me. I do not like the top power button as its hard to find by feel. I am use to hitting the end call key on my old treo 800w to turn on/off the screen.
