I've only seen them as crytsetup options.. I'll google for those..
I'm not sure if the "same key" problem exists in Fedora 16, I've tried setting it up this way and I'm able to boot but not resume.Simply, you can't suspend the device which contains the cryptsetup binary.
That's silly. Grub loads initramfs from an unencrypted /boot partition; initramfs knows about encryption and is able to mount root after I enter my key. There should be no technical reason why it can't mount the swap with the same key immediately after and tell kernel to resume from the now-available swap.
