FWIW there's a standard jack reporting API which has been merged into
ALSA and should appear in 2.6.27 or 2.6.28 (can't remember which off the
top of my head).  It doesn't provide a sysfs interface, just wraps an
input device ATM.  The intention is that in future it'll be extended or
wrapped to have hooks into the ASoC power management.
