My answer is off-topic to your question, but on-topic to what you try  
to achieve.

Are you sure the ICH7-based audio device is using the ac97 interface  
and not the HDA interface (hardware development decission, can't be  
changed with software)? If you are not sure I suggest to try to get  
this information somewhere. If it is using the HDA interface, your  
approach will never work. I suggest to have a look into the  
multimedia@ archive and search for HDA mails in this case.

Bye,
Alexander.
