imsd turns out to be fully public already (0.2.7 snapshot + emergency
stage 1 + the make build path) - no tag needed, same git-archive dance as
the kernel. callaudioshim was a load-bearing unpackaged home-dir script on
the phone (callaudiod replacement, working in-call mic mute); now an aport
autostarted at phase 1. kde-telephony's modem daemon autostart is hidden
via /etc/skel from the imsd package, mirroring the phone's user override.
