The loop thread is NOFREEZE, so it should work fine. Until you said it,
I hadn't considered md, but it shouldn't be too hard to add some more
code to check if the devices are part of raid arrays. The other devices
could be given the same treatment.

As far as setting them up again at boot time, I've just added proper
initrd support, so one will be able to do any configuration needed from
an initrd (provided filesystems aren't mounted), get suspend to check if
it needs to resume and then carry on in the rest of the initrd mounting
filesystems and so on.
