I'm having the same problem on a Thinkpad T400s under Ubuntu 9.10. In particular, the T400s has a single 1/8" jack for left and right speaker output and external microphone input. I'm using the Bose mobile in-ear headset. The sound output works fine. However, as in the original post, the external microphone doesn't appear in System->Preferences->Sound->Input; only the internal microphone appears. I tried installing linux-alsa-driver-modules-2.6.31-19-generic from the ubuntu-audio-dev PPA and upgrading other packages from the same PPA (libpulse-browse0 libpulse-mainloop-glib0 libpulse0 pulseaudio pulseaudio-esound-compat pulseaudio-module-bluetooth pulseaudio-module- gconf pulseaudio-module-x11 pulseaudio-utils), but none of this had any discernible effect. According to lshw, my audio hardware is:
