Yes, I see the problem you're trying to fix. It's just that this way  
it's going to bite pretty much every board one way or another. If it's  
just the randconfig style builds then bodging it in the CODEC drivers  
is probably more complete but OTOH it would be better to do it in a  
way that also ensures that the machine drivers are usable when  
enabled. I'll have a look and see how much trouble it would be to do
