For me, it's the other way around. Whenever we try to improve the 
generic behaviour of the codec driver, e g by adding configurable 
auto-mute, jack detection notification etc, these old models get left 
behind because the new stuff depends on information we get out of the 

By removing the model quirks, these machines can benefit from the new 
functionality as well.
