If FreeBSD 6.2 was installed after the dual-core CPU was there, it would
have automatically installed the SMP kernel, so you don't need to create
a custom kernel.
The easiest way you can check if the support is there by looking at the
output of `top`: if there's a column named "C" and it shows "0" and "1",
everything's ok ("0" and "1" are the CPUs on which a process is executing).
