[mythtv-users] how to keep /dev/video? and /dev/dsp? consistent

I use pre-install in /etc/modules.conf

i.e.

pre-install "this module" modprobe "that module"

which basically means before you load "this module"  load "that module"
first.  I use this to daisy chain a bunch of modules, so I dont lose the
/dev/dsp and /dev/video assignments.  However, when two devices share
the same module (ex. 2 bttv TV cards), then only ordering of PCI slots
seem to determine the ordering of the devices.
