The normal chkconfig interface still works with upstart, and the inittscripts are still in /etc/init.d, and symlinks are still in /etc/rcX.d, with upstart. /etc/inittab is only used to set the default runlevel in upstart, as documented in /etc/inittab itself, at least on my RHEL 6.1 system. But it's runlevel emulation, not classic SysV runlevels, and upstart is capable of event-driven daemon loading/unloading. The F15 and later systemd goes beyond that.
