I just looked for the first time, but this is what I can tell. In /etc/inittab:
si::sysinit:/etc/rc.d/init.d/rc sysinit
This is running /etc/rc.d/init.d/rc with an argument of sysinit. In
/etc/rc.d/init.d/rc, $1 (the first argument) gets mapped to runlevel.
[ "${1}" != "" ] && runlevel=${1}
It then starts executing scripts in ${rc_base}/rc${runlevel}.d.
rc_base is set in /etc/sysconfig/rc. I don't know how that helps your
bootsplash scenario.
