There is no kernel-2.6.9-42.ELsmp.src.rpm. SMP kernels are built from the same
source as non-smp kernels. While you are in make oldconfig, you can enable smp
just as easily as enabling the arcnet drivers. In your /boot directory are the
configs you need to run under make oldconfig to get drivers that have been
left out. You will have one for each kernel you have installed. It is an easy
way to see what has been done with a kernel you have installed.
