Not quite single mode, but what I have done in similar situations is boot with console=ttyS0 init=/bin/sh
which will give a shell on /dev/console before any init scripts have run. At this point mount -o remount,rw / and edit the inittab (you might need to mount /usr depending on your configuration). To get back, unmount the filesystems, remount root read-only, and either reboot or (from the first shell) exec /sbin/init -s to follow the normal bootup to single mode (Be sure you remounted root ro in this case or your init scripts will likely fail).
