 Strictly speaking, cpuid is not a privileged instruction, so userland can 
 already query the serial number by using cpuid directly if it is really 
 needed.  Given that CPU serial numbers were short-lived and are not included 
 in newer processsors (P4+), I'm not sure it is really worth it to have the 
 kernel print out the serial number on boot.
