My Desktop is a Dell Dimension XPS Generation 2.  I had lost track of this post here, and forgot to update it with new info about the problem.
I am now running Edgy, and still occasionally run into the keyboard locking up every once in a while, however, it seems much less frequent lately (or maybe that's just the luck of the draw and I'll end up getting it more later to make up for it... :P )

Anyway, I have found that when the keyboard locks up, I am able to unplug the PS/2 from the keyboard jack in the back, and then plug it back in to the Mouse PS/2 jack (I use a USB mouse, so that jack is free).
After this, the keyboard functions fine!
I think it must be some sort of weird race condition where the PS/2 ports get switched inputs for some reason randomly.
When I reboot and the ports are back to normal, I must unplug the keyboard and put it back into the port meant for it, so that it will work again.
