Because you cannot determine the frontend driver in advance for the
various av7110 dvb-s cards, the user either has to know what frontend
he has or simply load all frontend drivers.
Add this to saa7146_core.c:
If (the correct frontend driver can be determined by pci subsystem id)
request_module("ves1820" // resp. the correct driver);
As Holger pointed out, this only works if your have the modules
installed system wide via "make install". Otherwise loading the
dvb-kernell "ttpci" driver might use the frontend drivers from DVB. For
most of the frontend drivers this might work, but can introduce subtle
problems when the frontend drivers start to differ...
