Of course, make sure that your cpuspeed service

(this script enables/disables processor frequency scaling support, either using
the cpuspeed daemon or in-kernel frequency scaling support)

is enabled and running on your 2,3,4,5 runlevels.
You can do it manually (chkconfig --help) or via System - Administration - 
Services.
