Hi, no extra tools/daemons needed to scale CPU frequency - see http://technowizah.com/2007/01/debian-how-to-cpu-frequency-management.html ; worked for me on all computers I tried. you might also want to tweak HDD energy saving parameter (using hdparm) ; exact options depend on what capabilities your HDD has.
