Just donated, it's not much, consider it beer money
BTW, I'm now running 245-480 conservative governor given the info you posted earlier, it's still smooth enough for me, will see if the battery gets even better.
I would leave the max at 600MHz. Generally when coming out of sleep ondemand will jump to the max pretty quickly and ramp it back down. I'm using a widget to monitor battery temp and CPU speed, and you'd be surprised how little time the phone spends at maximum clock speed (even while playing music or using live wallpaper).
