You need to recompile your kernel with SMP enabled.
In the top-level Makefile ("/usr/src/linux/Makefile"), you'll find a line near the top which reads: #SMP = 1
Remove the '#' from the beginning of that line to uncomment it, then follow all the rest of the instructions for compiling and installing the kernel.
If you use a 2.1 series kernel (the development tree), then you'll find that SMP is the default anyway, so it should just work.
A long time ago someone made it possible to configure this just as easily as all the other options in the kernel, but for some reason it was decided to keep it hidden.
In 2.0, I believe that was because SMP was still experimental, but now SMP is extremely widely used and reliable, I don't know the reason for keeping it hidden.
