I don't think so. But, you can use any block device for swap. You can also use a swap file. Also, you can use sevral swap devices and files. Here's how to create a simple swap file:
dd if=/dev/zero of=/swap bs=512 count=(the number of 512 byte blocks that you want your file to have) sync (just to make sure that the file is dumped on the disk, and is not in a buffer) mkswap /swap swapon /swap
Though, I don't think that increasing yout total amount of swap will affect performance if you increase ram. Let's say you have 1G of ram, you don't need a 2G swap partition, unless there is something that I've missed.
