I'm not sure what gave me this idea, but I decided to comment out the swap partition in /etc/fstab and reboot my laptop. I did not run swapoff directly at any time.
I'm running more things now than I would ever dream of to hammer my 500MB of memory, but I still notice NO slowdown. This is the best desktop experience I've ever had for any OS on any hardware!

As you can see, I'm running a KDE environment. I'm going to try this in a gnome environment tomorrow.
This is on an HP Pavillion ze4800 I purchased at WalMart a bit over two years ago for ~$900.
From dmesg:

Hope this makes someone else's day!
