You can add a screen session to the inittab at a specific run level :
# GNU Screen on runlevel 4 scr2:4:respawn:/sbin/mingetty --autologin <user> tty1 linux Where <user> is your user.
Then configure grub to output to that device.
# (0) Arch Linux title Arch Linux Screen root (hd0,2) kernel /vmlinuz-linux root=/dev/disk/your_disk ro acpi_no_auto_ssdt irqpoll 4 initrd /initramfs-linux.img
