Look in /etc/sysconfig/kernel and you will see where it specifies your
default kernel type.  In single processor systems here, we've had some
random lockups that traced back to the use of SMP and so we don't use
the SMP kernels.  These problems happened back in the Fedora 3 days,
can't say now if it is a big issue.
