Hardware Buttons

I added the hardware buttons to the Hardware page.

My best guess is that the TI TPS65921B Mulitpurpose IC is handling I/O from these.  If so, getting the short- and long-press behavior to work on the Power Button would rely on the driver for this chip -- yes?

Android 2.2 requires 3 hardware buttons:  Back, Home and Menu. A 4th Search Button is optional. Assigning 4 of the NST's buttons to these functions and leaving the 5th user configurable would be ideal.  A second best choice would be to disable the 5th button.

I seem to recall seeing some posts about the Nook Button causing power drain problems with some modified kernels.  I will revisit that tomorrow...
