This is cool! I did it on my dual-boot laptop where I don't have the 
space (or the courage) to make a new swap partition. Here's exactly what 
I did in Fedora 9:

1. In my home directory:

  dd if=/dev/zero of=MyGiantSwapfile bs=1024 count=6000000

That created a 6 gigabyte empty file called MyGiantSwapfile.

2. Then:

  /sbin/mkswap MyGiantSwapfile

(On my machine, the command "mkswap" is not on the path so I had to 
include the path to it.)

3. Then:

  su -c "/sbin/swapon MyGiantSwapfile"

(Again, the command "swapon" is not on the path.
As I understand, this last command has to be repeated to activate the 
swap file, each time you log in. And you can de-activate it with "swapoff".)

Now you can verify that it worked by starting up the system monitor and 
looking at the resources. You can see that there is a lot more swap space.
