The swap partition does take care of swapping. But (and this is a big "but"!), swapping really, REALLY, slows down MySQL.
It is better to allocate less memory to MySQL than to depend on swapping. MySQL is designed to do efficient 'caching' of disk I/O with the memory you give it. but MySQL is assumes the cache id immediately available; that is, does not need to be swapped back in.
