I've tested with a swap on a "regular" partition and it works as expected. If provided with the right swap offset (as returned by swap-offset from a recent CVS), suspends and resumes. When provided with a wrong offset, refuses to do anything. I think we have to debug the swap-file-on-LVM case more thoroughly.
