See: /usr/src/linux/Documentation/smp.tex
(although it is pretty deep stuff, at least my my standards)
(if you don't have tex stuff installed, just browse the file)

edit /usr/src/linux/Makefile and uncomment the line that says "SMP=1"
(remove the "#" in front of it), and compile a kernel (ref kernel HOWTO).

That is all I have ever done.  There may be things you can do to
optimize the usage of both processors, but I never bothered.  I found
that if you run a bunch of small programs they will balance themselves
pretty well (example: run 10 instances of something to calculate pi).
One big CAD program won't balance itself unless it was written for SMP.

It is said that newer kernels (like 2.2.14) do a better job with SMP
than 2.0.36, but I have never tested it.

We all are.  You can be the world's expert on one thing, and you still
don't know a damn thing about the other 99% of it.
