I can confirm that behaviour for my T61p
BTW: Why does powertop only show either 0% or 100% and nothing between?

New Bug with b111a ?
My power management works fine when I first boot my Lenovo T61, but
after putting it into suspend mode it will always run on the highest
frequency.
Some additional info:
