The "classic" SpeedStep is not quite as straightforward as Enhanced
SpeedStep. IIRC you need to suspend the cpu before switching frequency
which takes ages speaking in GHz-terms and makes the approach estd
takes (involving multiple frequency-switches in a short interval)
unfeasible. Additionaly you have to cope with buggy ACPI implementations
or go for semi-official mainboard specific interfaces. This would be
some tough work and require access to a lot of different laptop-models to
get it working reliably.
