Yeah, it's on the K12LTSP CDs. You're looking for the kernel-smp RPM,
which will install in parallel to the non-SMP kernel RPM. It contains
the Linux kernel compiled with SMP support. If you are online, as root:

yum install kernel-smp system-config-boot

This will download and install the latest version of the kernel, which
has some important bug-fixes that the one on the install CDs will not.
It also installs a GUI tool for picking the kernel it will boot by
default. You can find it under Applications, System Settings,

There are other ways that you can make sure it boots from the smp
kernel. You could also just be at the console when it boots to select it
from the the GRUB bootloader menu, or you could edit /etc/grub.conf to
set it as the default (see the default=0 parameter). Note that the
default parameter is zero-indexed, meaning 0 indicates the first kernel
listed, 1 the second, 2 the third, and so on.
