What I had in mind was what the Parport PPS generator does, only with output through a GPIO. Since no LPT is there on the rasPi, this doesn't exist for it unfortunately, but the source code could serve as a template. > There are comments in the kernel PPS documentation for an echo mode.

As far as I understand the sources, setting up an echo allows a PPS client to register a callback function with the PPS device to be called when a PPS event happens. The default echo function simply outputs "echo: assert" or "echo: clear". I guess one could indeed toggle a GPIO from a suitably defined PPS client.
