++ - A suspend image would really help.  The only gotcha is (as 
always), USB.  You would probably need to create an image without
any USB devices attached, and then let probing take over after
you have "resumed".

There are several successful embedded solutions that use snapshot
images to great effect.  We should borrow liberally from their 
ideas.
