The message is trying to say (admittedly not very clearly) that that
particular cpufreq driver doesn't work with your cpu.  The loadcpufreq
script (from cpufrequtils) is incorrect for (at least) Celerons; see
bug #428248.  You can try p4_clockmod, but it doesn't seem to
accomplish very much in the sense of power saving (it does drastically
reduce system responsiveness :( ); see the above bug, and also the 3
bugs mentioned in the loadcpufreq script (#396117, #342014, #367307).
