I guess I'm wondering what value is added by exporting it as a
separate ALSA card.  Ideally it should be integrated into the
thinkpad's real sound card.  Otherwise sound applications will have no
idea that this separate mixer-only sound card has anything to do with
the main speaker output (as compared to the Skype headset I have
plugged into the USB port).  

I suppose it does mean you can use alsamixer to manipulate the sound,
but from the user's point of view, if it's not visible when they right
clock on the mixer applet (because it's not associated with the
laptop's primary sound card), is it really that useful?
