Yeah, I threw out a whole approach for the light circuit cause it  
might have been
vulnerable to this (assuming Ivan's mighty software defenses were  
overcome).
The fun part was avoiding any flickering as that entire chunk of  
circuitry is powered
on and off during suspend and resume.

And yes, there is only one screwdriver (a #1 phillips) required for  
all the screws on
the laptop.   I do find a small flathead useful in a couple of places.
