Hi!

No.

swsusp works like this

        stop all devices
        save state
        atomically copy memory into my_big_buffer
        start all devices
        write my_big_buffer into swap
        poweroff

It does not need explicit knowledge of where swap is. And I believe it
is reasonable that way.
