There is a Linux utility called Powernowd which I'm using on my
notebook. It slows down processor speed to 20% of normal when there is
little load, but automatically takes it up to 100% when demand requires.
I find it very useful, and have not noticed any appreciable slowness in
performance. As for how useful this is, I find that my cpu temperature
is 60 degrees Celsius without Powernowd, and 45 degrees Celsius with it.
So this is a major improvement.

Description: control cpu speed and voltage using 2.6 kernel interface
This simple client controls CPU speed and voltage using the sysfs
interface
to the CPUFreq driver in v2.6 Linux kernels. It does not depend on APM
or
ACPI, and it doesn't try to do anything other than control the CPU.
.
The name is somewhat misleading, as any CPUfreq capable processor will
work,
not just those from AMD. However, it works better on CPUs that support
more
than two speed steps, like those with AMD's PowerNow! or Intel's
Pentium M
series.
.
This daemon is less complicated than cpufreqd or cpudyn, at the cost of
absolutely depending on a 2.6 kernel with the userspace governor and
sysfs
support enabled.
