Don't get me wrong
I belive (still testing battery) that it saves battery.
When I reset all scripts to kernel default (via SEMAPHORE 0.62) I can select in SetCPU 3 options - smartassv2, ondemand and performance. I run CONSERVATIVE script - and I have 4 options in SetCPU - conservative, smartassv2, ondemand, performance. Again - I run save battery script in Semaphore - and still only 4 options in SetCPU. Shouldn't be here 5 options ???
Choosing Battery Save script just changes settings for conservative without adding 5ts opion ???
As semaphore kernel is very modular, governors are only loaded, if needed.
If they are not needed anymore, they are unloaded.
Except SmartassV2, as it has a bug. Unloading it would cause a reboot. So I decided simply to NOT unload it, once it was used.
That is the reason, why you can see only ondemand, performance on default in setcpu.
You'll see smartassv2, ondemand, performance once you used smartass, and the conservative governor only if you are just yet using conservative or savebattery setting.
