@ All of you people

I was not ok with the battery lasting I had been having. I think because I deinstalled and installed the batterypatch (KP version). So I checked "overclock" profile. i saw that I had too many frequencies active (FREQS), so I changed that. Now I only have 3: 500, 600 and 805, as my N900 can work at 805 MHz.
Governor is still conservative and smartreflex's VDD1=0 and VDD2=1.
I also raised Max CPU to 805, but that is just for power purposes, and still makes a better performance than with previous settings.

I think it works better now. If I'm not wrong was "vi" who pointed out that having a lot of frequencies makes the device slower and thus it sucks more power because of having to switch among a lot of frequencies.
I tell you just in case someone was experiencing more battery drain than before.
