FreeBSD 5 - What Options for SMP Kernel?

I just built my first 5.4-RELEASE system.  I want a SMP kernel.  The 
GENERIC kernel conf file contains this line:

device          apic                    # I/O apic

According to NOTES, this is all that's required to build an SMP kernel.  
However my dmesg does not indicate that both processors are being used.  
In version 4, these two lines were required:

options        SMP                     # Symmetric MultiProcessor Kernel
options        APIC_IO                 # Symmetric (APIC) I/O

I've searched Google but haven't found any definitive answers.  Exactly 
what lines do I need in my kernel conf and how can I verify both 
processors are being used?
