Marvell has done a great job on this for a preliminary enabling on their Dove
processor, please have a look into:

http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-lucid.git;a=shortlog;h=refs/heads/mvl-dove

arch/arm/mach-dove/swsusp.S

The code, mostly, is generic enough to be made common if you are
interested and have other platforms (with HDD or large NAND) to
test. x86 is, of course, the reference.
