Absolutely.  Way better than upstart, too.

Eg. you could do this (below), or even something more sophisticated,
from the /etc/init.d/mythtv-backend script:

    while [ ! -e /dev/dvb/adapter0/frontend0 ] ; do
       sleep 0.5

On my own system, I have a rather more complex script to wait for multiple DVB/V4L
devices to become fully present, and the script then creates unique symlinks for
each of them so I don't have to rely on particular cards being assigned particular
numbers by the kernel.
