The suspend2 patches do most of this already.  You can specify a default
suspend image that gets loaded on boot.  Kernel help says its for use in
embedded systems to make the system come back up in a default loaded state.

I not sure if it does compression and its a raw partition store in the
swap partition rather than a filesystem.  So it would need some tweaking.

We were investigating this on one of the systems at my old employer
Bitworks.  I never actually used it though.
