now WAITING for cf root xxkg2

Nope. At this time of posting only ZSKG2 and JPKG2 kernel is available which is 2.3.3

Bugeca is correct. The CF Root KG2 at present now is for KG2 roms that are Android 2.3.3 based, including the kernels. The only CF Root for Android 2.3.4 available now is KG1. Your Android maybe 2.3.4 but chances are it is running a 2.3.3 based kernel

Put your SGS2 on your bed near your pillow, somewhere it can measure your movement (on Airplane mode if you're one of those "argh it will give me kanker" types) and it will use the accelerometer to measure your movement while you sleep, comparing that to a database of movement to determine you're in normal or deep sleep phases (like your cpu lol - everyone is hard to wake while they are in deep sleep).

It will trigger the alarm when you are the easiest to wake - normal phase somewhere near your determined alarm time (if you set 6.30 am, it will might trigger 6.00-6.30, depending on when you're in normal sleep phase).

Sounds dubious but it really does work, for me anyway. YMMV though. Also, it does NOT work if you go to sleep at 6 hoping to wake up at 6.30 lol, it's NOT magic.
