Hmmm...I've just tried your script (v.1.3) on my N810 (running Chinook 2007-50.2). It seems to suspend the tablet just fine, and pressing the power (|) key reactivates the display. Unfortunately, after suspending, all other keys--the hardware keyboard, the D-pad, the Menu button, the Home and Escape buttons--are disabled. After pressing the power button, I can tap on the screen, but cannot do anything else.

Since I ran suspend.sh from a full-screen X-terminal window, I cannot close the window or change to another application, so I'm forced to reboot.

Have you seen this kind of behavior, and do you know of a fix or other method for suspending the tablet?
