I do this, though not on lvm. I have written a little script that unencrypts the swap partition and I've put that script into the initrd so that it runs before uswsusp tries to start up. It mounts and reads a key from my sd card and uses that key to unlock the swap partition. Essentially, you need to activate the encryption and lvm early on, though I don't think you need a static device node to do it. you need dev-mapper up, but I think it comes up really early and shouldn't be a problem. If you need more details, I can send you my scripts later when I'm on my laptop. A
