Can I upgrade my laptop with a Low Voltage Pentium M?

I have a Dell D600 which has a standard Pentium M. I noticed that the
Low Voltage Pentium Ms (as opposed to the Very Low Voltage CPUs) use a
voltage range that is contained within the standard Pentium Ms voltage
range. The following figures are for the 90 nm Dothan versions:

Pentium M 0.988 - 1.356
Low Voltage 0.988 - 1.116
Ultra Low Voltage 0.812 - 0.940

This got me wondering if it's possible for laptops to easily support a
low voltage version. Or does the voltage controller need to be of a
higher quality, to accurately provide the very fine voltage
differences that the low voltage versions require? Different speed
steps can require as little as 0.016 of a volt difference when
switching.

I assume that the BIOS has to specifically support a particular CPU,
which is probably going to be the stumbling block if the voltage
controller isn't.
Or can you use something like RMClock to setup custom voltage steps?

Hmmm!
