Or do what the system is designed to do and make udev rules so that
the dvbs card is always /dev/dvb/sat-card and the dvbt card is always
/dev/dvb/terrestial-card (or whatever naming system works for you).

Also under your scheme you risk mythbackend starting before the cards
are loaded fully, a combination of your sleep commands and the fact
that the script to start them is probably quite a long way down the
startup train.

If you use udev, you can write your mythbackend init script to ensure
that it loads after udev is finished, I read how to do this in the
mythbuntu forums, and will find a link if anyone wants one.
