Actually, the output of init scripts should already go to the console. When the kernel mounts the rootfs and calls init, it sends its stdout and stderr to /dev/console. If your rootfs is an initramfs, however, the kernel doesn't automount the devtmpfs so /dev/console doesn't exist when /init is executed. We solve this with the script in fs/cpio/init. If this is the problem, you'll see that the kernel reports something like "Unable to find initial console". The only thing captured by syslog are the messages going to /dev/log, which are sent out by some daemons. If you want this output to go to /dev/console as well, you can add something like ::respawn:/usr/bin/tail -50 -F /var/log/messages to /etc/inittab.
