This may work with ALSA.
That's it:
> 0000:00:1f.6 Modem: Intel Corp. 82801CA/CAM AC'97 Modem Controller (rev 02)
Very verbose lspci output for both the soundcard and modem give me:

OTOH, ALSA in 2.6.5 doesn't like the modem controller:

and 2.6.7 totally fails on both the audio and modem controller

I will try one of the 2.6.9 rcs one of these days and see if I can get things to work.
