Ok - I've narrowed it down.  A GENERIC kernel will go into S3 just fine 
on this laptop.  Removing apic from the kernel will break that.

I've also run into some bugs with having smp in the kernel and certain 
modules, so beware.

Now, I can successfully go into S3, but coming back out (using the lid 
switch button or the power button are the only ways I know of) seems to 
reboot the machine.  Maybe I should say that I can't tell if it's 
rebooting the machine, or if the machine just 'powers up' as if it was 
off.

How do I go about debugging from here?

Eric
