If you can find an executable that will toggle bluetooth, you could create a shortcut to it and name it Long_Power.lnk and put it in the \Windows Directory. Then any time you press and hold the power button for a few seconds it would run that app. I did this an app that toggles vibrate/ringer.

A similar way would be to assign that app to the long send key press in the "Buttons" control panel.

One other way would be with a program like AE button plus. You could, for example, set the d-pad button to toggle bluetooth on/off when you press if for a few seconds. AE Button plus has the ability to do this without the need for an additional program to toggle it like I mentioned in the 2 methods above. I personally would prefer this method, but to each their own.
