I've compiled the latest snapshot which includes that fix and made it
try to the guy who has the sigmatel codec. It still oopses but in
another place. I've double checked with #error that SND_HDA_INPUT_JACK
and SND_JACK is unset. The new oops backtrace:

I had troubles to decode this faulty instruction to the current source code but I've added some printk's to suspicious dereferences and told the guy to retry.
I'll be able to test the conexant one tomorrow.
Thanks,
