you should consider using some speed-throttling SW like cpudyn /
powernowd. They temporary throttle down the cpuspeed. See earlier
postings on this list.

If you have a acpi-enabled laptop you'll find this information in
$ apt-cache search cpu dyn
In this case "$ acpi -V" will also give you that information.
If no acpi is available lm-sensors may give you this functionality.
$ apt-cache show sensord
In 2.6 kernels those lm-sensors modules are already compiled in. You
still have to compile/install them for 2.4 kernels.

some powermanagement functions seem to not be enabled on your lappi.
even the cpu goes into a kind of sleep-loop if nothing is do be done,
there are much more efficient ways: throtteling down the FSB. Have a
look at the above mentioned tools.
Sometimes putting more RAM/other peripherie into the laptop disturbes
the airflow inside or these simple get hotter and so causes overheating.
