Thanks Tod!

So far the information I'm finding seems to say that one needs to
patch the kernel with the patches for something called a "PPSKit".
After that the stock ntpd from ntp.org should be able to use one of
its built-in refclock drivers.  (Also mentioned in the first
gatago.com link above.)

I was hoping that someone would just say that recent Fedora's kernels
contain all the stuff needed to do the PPS timestamping, but it is
looking like that may not be the case.
