You will notice while the results are not that significantly different, there is a shitload more DMA activity and IRQing going on when kp-settings is installed. While the CPU is not hammering some hardware on the N900 is. Notice the extra 100% ONs in the power domain table for with kp-settings. There is an ancient bug in kp-settings. I had issues with kp-settings since version 26. I never figured out why it caused all these wake ups I just know in some circumstances it does.
