I've started to work on proper sysfs support, but I quickly realized 
that a proper sysfs representation of the dvb subsystem isn't easily 
done, because you have a whole "tree" (ie. adapters with subdevices) 
that needs to be represented properly.

Another problem is that both PCI and USB devices can be registered, so 
you need to get the sysfs/udev registration right. This is were I 
stopped my attempts, because I already spend enough time to keep the 
drivers in sync with the mainline kernel.

Your help is really appreciated! I'm looking forward for your patches.
