Yes, this is the case-statement I changed last time.
As I did not have my changes (deleted long ago) I needed to redo it. Result is 
attached. The only change is duplicating one of those statementes.

By the way: why isnt there just
case "$TYPE" in
  block|scsi_tape|input)
    ...
    ;;
  *)
esac
as the code is the same in every place?

The reason for no longer doing this, is that I talked to linuxtv guys, and 
they told me they do not support such stuff :(

And well, to make it general applicable you need a good scheme to identify the 
cards.
A. by path: like above, fails with usb devices
B. by pci ids: fails with multiple identical cards, or with switching 
card-slots
Need to be improved for cards with multiple dvb-adapters (twin-tuner and 
similar)

C. by serial: some devices have serial numbers like usb, but not all


I just switched back to blacklisting all dvb-modules, and load them in well 
known order.
