Hmm..having rebuilt kernels for SMP support several times, I can't help 
but wonder if this is a clean install you're dealing with, or an upgrade 
from a previous release.

In either case, I'd cvsup your src tree with tag=RELENG_5_4, and follow 
the handbook kernel building instructions step by step.  Putting options 
SMP there should work, but I don't remember if it was already there and 
just commented out or not.  Here's what I have in my config:

# Enable Multiple CPU Support
options         SMP
device          apic            # I/O APIC

After you have the latest sources and those two lines in your config, 
follow the build and install process from the handbook.  Works beautfilly 
on all of the Poweredge servers I have here. :)
