The good -The one I found today is called "QuickDo" and it has a three day free trail.
The bad - It cost $7.99. And you still need the Home button to wake it up from sleep mode. This would probably be a problem for any app, as they aren't running when the iPad is asleep.
Emulates both the Power/Sleep and the Home buttons. Could save a lot of button clicks, especially it yours is going bad.
There may be others, look under the Cydia - Sections - Tweaks.
