I think there are a bunch of other devices that need stuff from userspace
before they fully init, namely the ones that load proprietary firmware
images. Will an approach like that work here?

Alternately, we could have a "virtual module" called mixer-settings-n,
which when requested would tell modprobe to call a program to do its
fiddly things but wouldn't actually load a module.

The virtual module idea is ugly, yes, and perhaps what's needed is a more
generic userspace hook interface. Something that merged what
/sbin/hotplug, /sbin/modprobe, and the much-talked-about devfsd-like
notifier are supposed to do.
