So for some reason XDA wasn't letting me post until now..I sent a PM to the author but that also mysteriously didn't go through (not in sent box) and now it looks like I can post! So here goes.
Just wanted to note that when I start the script (from the beta) I quickly got a lot of things flashing on the console which were errors about not having cpu1 etc. (lost the exact error message sorry). I don't have a dual core so this is expected but you might want to hide the errors.
I was also having problems I think having the script to stick or seeing if it was running. The minimum frequency always seemed to reset to something and it always said it couldn't find the Frequency settings file. Pretty sure other init.d stuff is running so not sure what's going on.
This may be a silly question, because I previously used CPUTuner and noticed something similar, but is ondemand the only governor that allows the kind of scaling used for the profiles? I would love to use smartassV2 because I've heard it's similar to ondemand but has better battery management.
Also thanks, when I was fairly certain the script was running I got about 2.5 days (mostly idling, but still) on battery, which was unheard of previously!
