dual cpu under linux?

i have a dell poweredge 2550, dual 1.13ghz cpu. bios sees both cpus. i am running centos 4.4 and installed and booted the smp kernel.

uname -a
Linux myserver 2.6.9-42.0.3.ELsmp #1 SMP Fri Oct 6 06:21:39 CDT 2006 i686 i686 i386 GNU/Linux

cat /proc/cpuinfo  | grep proc
processor       : 0
processor       : 1
When i run 'top', i do not see cpu0 and cpu1, only see Cpu(s). It makes me think the system is not using both cpus. At work, we have quad cpu systems and running top shows all 4 cpus. Do i need to do anything else to use both my cpus?

You could also use a monitor like gkrellm or conky to see the 2 processors in action over time; these are both fairly nonobtrusive solutions.
