use more power of the rc9.
The rc9 power consumption is comparable to the 3.0 kernel (about 7W), the daily use 9W!
Powertop shows these devices using 100% of power, that the other releases of kernel didn't use:
 Uso Eventi/s Categoria Descrizione
            100,0% Device Dispositivo USB: Globetrotter HSDPA Modem (Option N.V.)
            100,0% Device Codec audio hwC0D0: Realtek
But my HSDPA modem isn't in use and turned off in network manager.

The first distribution I used on my netbook was Ubuntu 10.10 Notebook Edition, and it has 6 hours of battery life and 7 hours with wireless turned off.
I tried Ubuntu 10.10 by live with a usb drive, but I don't have the results I expected, so I'm going to install that release.
