It is interesting that I did have this issue with my first Compaq DL380 load with slightly faster dual PIII's

Centos 4 always found both processors automatically...

hmmmmm, now... what part of my brains have done fell out my ears that I am not seeing the obvious solution on this one???

After searching for quite some time, I concluded that the info on this returned way too much noise...

Thanks in advance...

If you look carefully I think you will find there is NOT a CentOS/RHEL5 SMP kernel, just one does the whole deal. There is a -PAE kernel that is for more than 4 GB of RAM, but apparently there is no performance penalty with using a single kernel for both SMP an uniprocessor systems.

when you do a top and then use 1 and enter does it show both procs?

I don't see anything wrong with your kernel. The kernel version matches between the uname output and the kernel rpm. Apparently CentOS 5 found both processors (SMP in uname). Because a single kernel takes care of both smp and non-smp in CentOS 5, you cannot tell by the kernel package name, but if in doubt, do a 'cat /proc/cpuinfo'.
