You don't have job control on /dev/console because it will never become a controlling tty automatically. But if you make it your controlling tty with the right ioctl() you'll have job control.
In fact the latest sysvinit does this for process spawned from the 'sysinit', 'bootwait' and 'wait' type lines in /etc/inittab and that works fine.

That would be extremely c00l ;)
