[Kevin Klues]

Of course we can discuss this.... I just needed to get something in 
there so that I could get the potentiometer up and running for use with 
the TDA5250 RF Power settings.  I agree that this interface is way out 
of datemyself, but I was trying to get somehing written so that the 
radio component will be somewhat complete for the deadline of the 2nd.  
Maybe I shouldn't have put it in the main interfaces directory already 
without it having been discussed, but it can always be modified once we 
come up with an agreed upon interface.
