Hi Gerard,

You'll most likely need to repartition your hard drive in order to
increase the size of your swap partition. (If you're using Logical
Volume Manager that may not be the case.) You may not need to carry out
a complete reinstall to repartition your disk e.g. if the disk has a
separate /home partition on either side of the swap partition, you could
backup your /home, then boot into single user mode or use a Live CD to
delete the /home partition and then increase the size of the swap
partition using this new free space before recreating your /home partition.

You don't say what size, your current swap partition is but I'd imagine
you should get away with using whatever you're currently using seeing as
 you now have an extra 768MB of RAM to play with. However if you use
suspend to disk, then you *will* need to increase the size of your swap
partition to at least the same as the amount of RAM installed.

The following link may be of help to you (even though it's written for
Ubuntu users, it should apply to all GNU/Linux distros):
