Sterling, 

Which kernel are you running?  I recall that the PPC kernel needs to be 
compiled with SMP enabled, and that PPC distros (at least in the past) had 
to provide a separate SMP kernel.  What does uname -a  say? 

At the boot prompt, hit the <tab> key to see if there is an SMP kernel as an 
option. 

Regards,
Henry
