To disable single mode, you basicly have to patch /sbin/init. (This is actually
easier than it sounds, if u can get your hands on init source code.) You might
be able to get away by disabling runlevel 1 in /etc/inittab (or making it
the same as runlevel 3).

There is no way to stop a bootable CD. This is above the init level, above
the kernel level, and above the bootloader (lilo/grub) level. You can try to
disable this option from the BIOS, but even that is easy to work around.
