Yes I have kernel-power. I recommend you use version 46. It's very stable in Maemo (I never get a reboot with it).
You can use stock kernel for this, but it's outdated to PR1.2 in NITDroid.


For those who want to remove NITDroid from eMMC:
Remove those folders inside /home: bin, data, dev, etc (symlink), initrd, lib (symlink), mnt, proc, sbin, sdcard, sys, system, tmp, usr.
And remove those files inside /home: default.prop, init, init.nokia.rc, init.rc

The folders user and opt belongs to Maemo! Don't touch them! Everything else can be removed safely.
