Perflock is disabled via kernel module from SetCPU. If you use kernel without perflock, then you should use SetCPU or similar software to set some profiles. Stock kernel in Voda ROM also had some problems with ondemand governor (dunno if this is still the case with this one) forcing the proc to the highest frequency most of the time which is not good for your battery I guess. Maybe it is not such a good idea to disable perflock with this kernel after all so here is how you can enable it again:
adb shell chmod 644 /data/local/init.d/90perflock adb reboot
Thanks for all your work!
