Help Restricting buttons so only power button wakes up phone?


I want to restrict the buttons on my Optimus T so when it's asleep (screen dark), only the power button on top will wake it up.

Everyone else seems happy about being able to press any button to wake up the screen, or think it doesn't matter because it goes back to sleep in 10 seconds. I pocket-dialed 911 four times in one hour yesterday. Obviously the emergency call button needs to be accessible as soon as the phone is woken up, but I don't need every button on the phone to expose that vulnerability.

So, is there a setting or app that will lock down which keys wake up the phone?
