Congratulations on your work. Great improvement on the N900. My experience with kp49 has been great. I use DSP profile adjusting minimum clock speed to 500 MHz and maximum to 950 MHz. Always. Using less than 500 seems to cause breaks on audio playback of certain files (The Economist Podcast is one of them). The minimum frequency seems to change little the current consumption when the phone is on standby. Battery and speed patch seem to interfere with kp49 use of smart reflex. I found I had to remove them. Now, I get almost 24 hours of standby with skype conected on WiFi (my minimum use). Apart from eventual bursts of current comsumption (100 to 280 mA), my current keeps down between 18 and 50 mA. I guess the greatest benefit of SR is when you are NOT using N900's features (stand by). Great job!
