As you mention, it remembers me about an article that said 
that a long term goal for Linux would be to be able to configure 
stuff through small devices, rather than /proc if I recall 
correctly, for configuration. That is you'd do:

echo 12211000 > /dev/dvb0/frontend/frequency
echo H > /dev/dvb0/frontend/polarity
echo 22000000 /dev/dvb0/frontend/symbolrate

etc. 'cat' the same to see an ASCII version of the current 
state. Then bingo, easy debugging from an ordinary shell, 
instant bindings for any scripting or otherwise language, 
complete removal of the C API, and no nasty ioctl (which 
is one of the great uglyness of Unix) anymore.

I don't know if this is something already started in 2.5 or 
just a mere proposal which is floating around. If there's no 
infrastructure already  in there, it would arguably not be 
wise to do it alone in DVB. It does require devfs or some 
equivalent of course, and I suspect old style devices may 
still be supported in 2.5.
