I just realized that the above is due to my using
linux-backports-modules-alsa-karmic-generic

A clean & fully updated karmic does not have this, and instead has:

$ cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.20.

My apologies; purging linux-backports-modules-alsa-karmic-generic gets
it back to the above 1.0.20. Of course doing so removes the added
additional internal mic options (Mic B, Mic C, Mic E, and Mic F) so the
internal microphone no longer works (and speaker & headphone still play
at the same time).
