Yes, the same hardcode major/minor number is in vidinput_names.cxx for
vidinput_v4l2;

concerning a patch, I can't provide a common solution which works on
Linux and FreeBSD because I'm not a C++ programmer; I only could hack
the code as shown above so that it will work in FreeBSD; maybe Steve
should just put this into a patch file for the /usr/ports/devel/pwlib in
the FreeBSD ports tree; Steve?
