service cpuspeed stop basically just runs "/etc/rc.d/init.d/cpuspeed 
stop".  That's independent from having a /etc/rc.d/rc0.d/K99cpuspeed 
script that runs at shutdown.  However, the other thing that the stop 
does is remove the /var/lock/subsys/cpuspeed file.  These files are 
pretty tightly integrated to our service system and forces most services 
to get explicitly stopped.  Might be worth examining how useful the lock 
file is and whether *every* init script should use it.
