This kernel is built from a custom modified source by me (I've added and modified some things to an updated SGS2 source), I've tried to modify it to get the lowest battery drain, so this kernel should stay in a step between performance and battery, if you like some more performance you can download SetCPU, or other custom app to modify freqs and default governor.
-For XXKG1/G2/G3 (should work with olders too)
-Modified Freq range 11 steps (200-400-500-600-800-900-1000-1200-1400-1504-1600 Mhz)
-CPU UV sysinterface (thanks to ninphetamine)
-Modified cpufreq.c to force processor to go step-by-step in freqs.
-Default Freq: 500-1200 Mhz ondemand (the best to get low batt drain, should drain lower in sleep)
-Lowest maximum freq blocked to 400mhz (so if you put 200-200, it will run 200-400, locked due to better performance)
-Available governors: interactive-smartass-conservative-userspace-powersave-ondemand-performance (custom modded smartass, ondemand and interactive governors)
-CFQ Block IO Scheduler (Available: no-op, deadline, cfq)
-Modified Initramfs from saturn_de (thanks to him and Chainfire) - I've added some values to this init.rc to get lower battery drain and some performance. (some different from saturn)
-CWM 126.96.36.199 Recovery
-Disabled Profiling support and debugs, added ThumbEE, Improved Control Group Support.
-Added some CFQ IO tweaks
-Changed dalvikvm heapsize to 60m (this should improve performance on tasking)
-Touchscreen fix added (thanks to vicenzo91)
*int:fast is not included due to performance problems.
*not compatible with tegrak OC (tested with SetCPU)
test with performance 1504mhz, vfs_cache_pressure=100 and dalvik 64m (default vfs=70, you can modify it downloading Sysctl Config from Market)
*set samsung-update1 as base (fix reboots)
*added slqb patch
