Hi there,
I used to use Titan's kernel but gave it up because it messed up with 3G call reception, 3.5G data and wifi signal, and the load ideal causing freezing on my phone.
Do you have similae draw back when using QCPUfreq? If not, I will give it a try.
I am not trying to OC for games, but I would love to save some battery or make my N900 more swappy.
