Maybe in the old days, but most modern systems allow you to put a label on a swap partition. I don't know how to put one on an existing swap partition, but if you look at the man page for mkswap, you will see a -L option (if your system supports swap partition labeling). So, just recreate your swap partition with the mkswap command and use the -L option...
