Unfortuantly, there is no way for pm-utils to know that is the case
without actually trying it. Just because you have less swap space than
system memory does not mean hibernate will fail no matte the method you
use, the system will throw away memory it can load from the hard disk
elsewhere (filesystem cache and the like) if the memory will not fit in
hte amout of swap space available. Uswsusp and the in-kernel hibernate
have to do this anyways, because the way they take a snapshot is by
freeing up half the memory and then copying the non-freed half over the
pits that got freed before writing the snapshot to swap space.

There is no way for pm-utils to know this in advance. Sorry. Might I
suggest making your swap space bigger?
