True.  That's the downside.   The upside is that we don't need to create a
new API to allow the piggy-back.  After all, the real soundcard module could
get loaded *after* ibm-acpi... or it could be removed before ibm-acpi.  The
"piggy-back mixer control" would need an API with full hotplug semanthics.

If they got a mixer applet worth something, it will list two cards, or allow
them to have two instances, one for each card.
