Two things here.

One: many (mosgt) laptops allow you to change the actual CPU speed to save
power. look into the linux-based utilities package (if any) for your brand
of laptop, or (wince) install Windows and use the manufacturer's utility.

Two: Bogomips are not very scientific. I have seen them off by a factor of
6, with no apparent change in actual performance or more exact benchmarks.
take 'em with a grain of salt.
