I tinkered with two different methods, both of them use Gordon's WiringPi library to manipulate the GPIO. One of the setups uses a PowerSwitch Tail II to power off the entire machine and the other method used a simple relay to toggle the reset button. My preferred method was the firs method because it FORCED power off no matter how frozen the mobo was.
By the way - the close observer will notice that the PowerSwitch Tail is really just a relay enclosed in a box. I prefer to use it when handling 120V AC so I don't make shiny sparks.
