fw190 they are auto activated

but if you know that N900 can't take handle starving and ideal
then i don't recommend this update for u

although you may wanna try it
if anything went wrong
your N900 should reboot and say the custom settings where not loaded
in that case remove it directly

ALTHOUGH something wrong may happen with you
IT'S AT YOUR OWN RISK

//EDIT

it has nothing to do with CSSU



//EDIT AFTER YOUR EDIT

i will release another package called batterypatch-nonkp
it will be just like the old version
for you and others who are not lucky with their N900s

and you can download the older version from
