I am wondering what's the reason of breaking this current rule as it
sounded so clear...So if cards all delivery systems are mapped as an
adapters under same frontend, there must be a some method for querying
which of those adapters are tied together. Did Manu say whether that
info can be get via dev tree, via sysfs or by using some new ioctl?

And if the patch wont go in, it means that hvr-4000 owners needs to
maintain in addition of the vdr-patch, also a patches for all plugins
that the patch breaks :-(. On the other hand, if the patch would be
accepted to vdr before 2.0, I am sure that all plugi-ns would be adapter
to work in couple of weeks to work with the new interfaces.
