A correction, the Fedora Man page for cpuspeed says

"Many modern Linux systems support in-kernel  cpu  frequency
       scaling. The cpuspeed daemon only works in conjunction with
       the ’userspace’ frequency scaling  governor.  Other  gover-
       nors,  such  as  ’ondemand’ and ’conservative’, rely on the
       Linux kernel to adjust cpu frequencies on the  fly  without
       the  need  of  any user-space assistance, such as that pro-
       vided by cpuspeed.

       Red Hat and Fedora distributions employ a unified  configu-
       ration  file for both scenarios, as well as a cpuspeed init
       script that will configure either cpuspeed or in-kernel cpu
       frequency scaling, as appropriate.

       /etc/sysconfig/cpuspeed, configuration file

You can also put in the min and max speeds

/etc/init.d/cpuspeed in a appropriate way

That will solve all of the problems if it is due to scaling
