first of all thanks for your kernel, looks like you put much time into your work on it!
i'm trying out your kernel right now.
i'm not using setCPU, though i'm using the ROM Apex 1.0.2 which has a builtin overclocking settings, like i can set min/max cpu frequency , cpu governor and voltages.
i have set 350/1350 mhz and undervolted a bit.
i have cleaned cache and dalvic cache after i flashed your kernel.
IMO, gallimaufry is rather laggy, honestly i tried it only for 1 minute and couldn't stick with it anymore..
i'll now use aggressive governor a few days, which has a good first impression on me, and then report back here!
if you have any idea why gallimaufry is laggy for me, or need more information, let me know.
