You better read further info about suspend in Debian and what are your
options ;-)

Suspend to disk (hibernation) uses swap space to put the image data there
when you trigger the hibernation scripts, so you need to have this value
adjusted in order to success.
What happens when the swap space is too small to fit the image? Dunno,
but I guess it will just fail and give the user the usual warning (on
screen, on logs...).
