The headphone jack sensing issue is in the alsa driver. None of the packages you mentioned include the alsa drivers; the drivers are included in the linux-image and linux-backports-modules packages. That is why I am working on incorporating the patch into linux-backports-modules which provides backported alsa drivers.
