I'm not familiar with the Sony AF confirm chips unfortunately, only those for Canon.
The chip isn't mounted to M42 lenses, or limited to them. They are mounted to the Canon EOS EF to M42 adaptor, or EF to Pentax K, or whatever other adaptor.
I have since read that a few people have fitted them to the Samyang lenses too.
Edit: I haven't bothered with programmed chips. It is only for EXIF data.
