It's long time now I do not tweak kernel-power parameters (the last time was 21 May 2011).

I don't remember right now why I have choosed to set 'powesave_bias' parameter to 20, but for sure I set it like that after googling the subject, testing somes values and finally leaving the one I feeling the best ...

Since I don't play with injection driver, I cannot say my latest build accept or not this one, but I have removed 'atop' kernel patch causing many troubles (camera was no more usable with these 2 previous patches...).

Also, dpkg -i kernel-power-packages steps are more easy than dpkg-buildpackage ... I think it's better to check it by yourself, and come back here to report.

Hope it help ...
