I ran powernowd in my notebook (Athlon XP-M), and everything went OK.
So far, powernowd seems to be working better than cpuspeed; the machine
is cooler when idle but runs faster at battery mode.
Thanks everyone for the help. This is really a great place!!!

Someone mentioned powernowd. It did not work on my Athlon XP system:
powernowd: PowerNow Daemon v0.90, (c) 2003-2004 John Clemens

PowerNowd encountered and error and could not start.
I'm guessing that you have ACPI turned off. You need ACPI and the
files in /sys/devices/system/cpu/CPU0/cpufreq/ to use powernowd.
Nope - this is not true. cpuspeed/powernowd work with APM (on a P-M
laptop)
Okay, I jumped the gun. It is sysfs and the cpufreq module that are
needed. It is still probably the case that the directory I mentioned
is not populated. Probably either the powernow-k7 or powernow-k8
module needs to be loaded. Most likely the k7 module.
Are you sure you have a mobile CPU - and not a desktop CPU (in a
laptop shell)?
Or more directly, does the CPU support frequency scaling?
What does 'cat /proc/cpuinfo' say?
