The Yocto/OE build for the 410c uses the kernel pointed by this recipe
I double checked, and the patches mentioned in this thread were indeed merged into the release kernel.
Just for completeness, I re-generated the 16.06 release from the Yocto/OE recipies and I can confirm that /dev/ttyGPS0 is present and the GPS utils are installed.
However, to get the NMEA string, I still had to manually boot the DSP (so the GPS starts)
$ systemctl start qdsp-start
