Unless your system has exactly one CPU without hyperthreading and with exactly one core this is the correct bahavior, one tux per logical CPU. If you just want a single tux you can run your kernel on a system with only one logical CPU, boot it with maxcpus=3D1 or rebuild it with CONFIG_SMP=3Dn... though in those case you will not be able to benefit from all of your CPU's resources..
