A kernel with SMP support is not impaired by a uniprocessor system.  The
"detection" is done by the kernel, most likely Redhat installs an SMP kernel by
default no matter what.  And if it's not enabled, it's just one option in the
kernel config to set to Y.  Or to get a precompiled kernel for.  Very simple
setup.
