If you do "apt-cache search kernel-image" you can see all the prebuilt
kernels available for install. The ones with "-smp" are the smp-enabled
ones.
The command
apt-get install kernel-image-2.4.26-1-686-smp
should install that *smp-enabled* kernel, and reconfigure grub/lilo to
provide an extra menu entry at boot time to boot into that kernel [at
least it does with Sarge]. Of course you have to select the appropriate
kernel image for your CPU type, etc.
NB: I haven't used smp kernels myself.
