I am not sure and I cannot test it right now, but for last few years if
I was in need of single user mode a kernel parmaeter 's' was doing its job.
So, check whether:
kernel /boot/kernel-2.6.8-gentoo-r3 root=/dev/hdc7 s
works.
It should be the same as 'single' but maybe there is some magic in it ;-)
'man init' has some info about runlevel 'emergency' or '-b' which promises
to enter single user mode without running any scripts from /etc/inittab.
kernel /boot/kernel-2.6.8-gentoo-r3 root=/dev/hdc7 emergency
I believe that's what you're looking for.
