[K12OSN] Dual Core Kernel optimizations (a little off topic)

Fedora Core 6's default kernel is SMP (Symetric Multi-Processing) and will see
the Core 2 Duo as two CPUs. Earlier versions of Fedora have multiple kernels,
be sure to use the SMP kernel. FC6 sometimes has problems correctly
identifying the kernel architechture, so make sure you get the right kernel
upon installation. My laptop's Core Duo (aka Centrino Duo) was mis-identified
as an i586 so I had to rectify the problem myself (you may not have the
problem on the Core 2 Duo, which has a different lineage than mine).
You won't have to "tweak" anything to get load balancing between cores and
there is no provision for changing the default CPU behavior in the way that
you suggest.
