  The current intended approach for suspend to disk for OpenSolaris 
is just that:  write the statefile, but enter S3 instead of S4.  
Resume will be quick if no power loss, but there will still be a 
resume.  Of course the penalty will be a longer suspend time, but for 
those that want the quick suspend, they can just do suspend to ram.
