If there's too much memory in use when hibernation is attempted, an attempt will be made to free memory, which could involve pushing some pages out to swap. You therefore probably want swap space to be at least as big as the amount of memory you have, unless you're using the image compression support that I think uswsusp has. Please don't forget to post your code - we can then incorporate it in vanilla and you won't have to worry about keeping it updated.
