If you install FreeBSD 6.1 then you can choose between a generic kernel 
without SMP support and an SMP enabled kernel. These kernels are named 
"GENERIC" and "SMP". If you missed that point you can install it 

  # mount /cdrom
  # cd /cdrom/6.1-RELEASE/kernels
  # ./install SMP
  # echo 'kernel="SMP"' >> /boot/loader.conf
  # shutdown -r now
