Ah, here you go:

https://en.wikipedia.org/wiki/Uswsusp

It can already do encryption. If you see problems there, patches will
be gladly accepted to fix them.

If you want to maintain uswsusp in kernel tree, I guess that would be
an option, too.

If you want to just help swsusp, I have some patches that reduce
duplicities between x86-32 and x86-64. It would be cool to clean them
up and get them merged.
