Busybox init's console finding logic is a bit strange (see init/init.c 
function "console_init").  It's probably looking for /dev/console, which is a 
character device major 5 minor 1, which is not the same as /dev/tty (major 5 
minor 0) which is not the same as /dev/tty0 (major 4 minor 0).

It could be any of those.   Or none.  Maybe it's autodetected that you're 
using a serial console, or you're using a sparc, or devfs, or... :)

You could always check and see what you've got, and then open whatever device 
you _can_ write to and stick fprintfs into the code to see what it's doing...
