It solved all my problems.

It comes with a deamon which loads on startup. So, the values for hdparm etc it loads are not lost after reboot for example. I changed the "on battery" and "on AC" hdparm parameters as suggested in this thread, and now I have no more problems with increasing load/unload cycles. Moreover, after playing a bit with the rest of the settings, now the consumption of my lenovo t60 on battery is only 13.5W !!! -- as much as it consumed running windows that came with it (that was before I switched to ubuntu. After I did that the consumption never fell below ~18Watts).

I really hope people help this guy and start shipping this nice piece of code with ubuntu!
