I was late to the seminar, and didn't hear that part, so I might be wrong
here, but what he might be thinking is that the GPS, at least the C129 GPS's
don't sequence automatically to the missed approach point, you have to do it
yourself. Other than that, I looked at the AIM, and as long as you have the
non-GPS equipment required to fly the missed, and everything is working, it
looks to me as if you can use the GPS to actually fly it.

That's my understanding too - the substitution rules are only for
planning an alternate, but have no bearing on what you do (assuming
everything is working and no RAIM issues) once you're in the air.
