How can I replace a tty using getty with qingy on ubuntu 12.04 or later?

http://unix.stackexchange.com – Qingy is a getty replacement. I'd like to use it for a tty terminal on Linux Mint 15 (in hopes of getting tmux to get proper 256 colors in tty which fails with fbterm) which means replacing getty. I'm not sure how to do so, as it says I need to edit /etc/inittab, which doesn't exist in current versions of Ubuntu. (HowTos)
