No, i do not think so:
if I do not load the processor, my machine goes only down to 600MHz
instead of 50MHz...
..there is more battery consumtion and more fan usage, which is not a good
idea, because the fan is getting louder after 1 or 2 years!

on my last unit (T30), they did'nt replaced the fan as warranty and the
fan was quite loud after one year of using it, without acpi running!
