There is a new system called dvb_attach() that makes those front-end module
dependencies dynamic.  They don't show up in the list of module
dependencies from modinfo and don't need to be loaded before the module is
loaded.  Instead, dvb-ttpci will dynamically load the front-end modules
that it needs, and only the modules that it needs for your particular card.

If you are trying to auto-load the modules without installing them you can
disable dvb_attach and get static dependencies back.
