Just out of curiousity, what are you going to do to them?

The suspend thing has been an issue I've been grappling with for a
while. Eventually, I ended up taking the debugger out of the kernel,
running xlock on suspend, and running shutdown with a two minute timeout
on wakeup. (The idea is that that limits the amount of time an attacker
has to get to the contents of memory before it goes away.)
