Since I did not find a better solution yet I start a new kernel thread
that takes care of poweroff when getting the power button interrupt.
In this new thread I then send a SIGUSR1 to init, but you could
probably call "execve("/sbin/poweroff"....) " as well.

Of course I meant SIGUSR2. (Busybox') init powers down then...
