Unfortunately, I'm falling asleep right now and can't quite think straight,
but if you want to stick printfs into init what you can do is
open /dev/console (or whatever output device you know works for you) and put
fprintf() or dprintf() statements writing to that file with your debug info.
Then you can see what it's actually doing.
Also, I find qemu highly cool for debugging this sort of thing, but User Mode
Linux might also work for you...

I do not think it means what you think it means.
