What the others said is correct, however this is my setup. I have not made the plunge into AMD64-bit, so I am just running a kernel with -686 at the end. This detects my dual-core and runs everything just fine. My current kernel package (from Ubuntu) is 2.6.15-23-686, though the latest available is linux-image-2.6.15-25-686.
Another thing that is helpful, to see how your system is handling the dual-core, you can run the 'top' command from console, and then hit the '1' key. In Ubuntu, this shows me the loads on both my cores.
