You need a kernel with -smp in the name to have both cpu's detected and most likely you want -k8 in the name as well so it will be have the best support for the processors. Unless ubuntu does things differently than Debian you should get the choice of which kernel to boot at the Grub splash screen.

Good to hear you got it going. What is the speed difference between the single/dual kernels?

K7 may be the best you can get using a 32bit system. I know you can get the -k8 on a Debian amd64 system perhaps if your install is not too old you may want to move to the ubuntu 64 bit install.

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.
