You are free to uninstall the SMP kernel packages.  Unless you have
multiple processors, you'll actually get better performance using the
'normal' kernel.  If your processor has 'hyperthreading' or a similar
feature, you might want to consider disabling it.  Hyperthreading will
look like multiple processors to the kernel, and the SMP kernel will try
to take advantage of it, but this will actually usually result in a
small performance hit, depending upon how you use your system.  Without
the SMP kernel, you will get no benefit at all from the hyperthreading
