Ok, I merged Julio's scirpt in misc/15648.

* If only mixerctl=YES:
	It works as ever.  It simply sets /etc/mixerctl.conf to /dev/mixer.
* If mixerctl=YES and savedmixers="mixer0 mixer2 blahblah":
	It saves and restores each mixer in $savedmixers.
	/etc/mixerctl.conf affects as ever.

Other comments?
