Hmm, isn't this kind of bloated?

Most of the drivers have functional dependencies, so that loading the 
driver means basically modprobe'ing the core driver + modprobe'ing the 
frontend driver, ie. for a
- av7110 dvb-s card: modprobe dvb-ttpci; modprobe ves1x93 (or some other 
driver)
- av7110 dvb-c card: modprobe dvb-ttpci; modprobe ves1820
- twinhan dst card: modprobe bttv card=0x71 i2c_hw=1; modprobe 
dvb-bt8xx; modprobe dst

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.

So perhaps a small howto that tells the user which cards might have 
which frontends would be best. Most newer cards (for example the 
Twinhan) only have one supported frontend, so this would be easy.

The benefit would be that the user would get to know what frontend he 
actrually has... ;-)
