stderr actually is mapped to a pty. The problem seems to be that getty can't set /dev/console as its controlling terminal because it's already the controlling tty for init, which is in a different process group. Thus getty ends up with no controlling tty, this is inherited by bash, and thus bash cannot set up job control.
