Yes, until we manage to copy what ALSA does in this case, this
is what we'll have to do.

The following patch works around the misdetection of the CXT48
codec as a modem by the OSS ac97 driver.

We should fix the crash itself too. Andrew, I'll send you some
a couple of patches on that later.

BTW Alex, if you have the time please determine whether ALSA
works properly on your machine.

Cheers,
