cx88-dvb depends on cx8802, which depends on cx8800 which depends on cx88xx

so, the && logic above is incorrect, and irrelevant... all that must be 
modprobe'd is cx88-dvb ... it will automatically load all of its 
dependencies.

This is already the case.  bttv is the analog driver, dvb-bt8xx is the 
DVB driver, and it automatically loads (bt878 and) all supported 
frontends EXCEPT dst.
