I didn't study deeply how much that define may change the code. I only
know that if PPS_API_VERS_1 is not defined the NTPD default
configuration changes.

Maybe, or maybe not... first of all we should verify that the problem
is in that define. Currently we are only supposing. :)

However I think the file timepps.h should be changed as follow:

   /* --- 3.2 New data structures --------------------------------------------- */

   #define PPS_API_VERS_1          1       /* Keeped for NTPD back compatibility */
   #define PPS_API_VERS            PPS_API_VERS_1
   #define LINUXPSS_API            1       /* mark LinuxPPS API */
   #define NETLINK_PPSAPI          17      /* we use just one free number... */

In this manner NTPD should restart working with proper configuration
but we still continue patching the drivers using LINUXPSS_API to mark
LinuxPPS code.

I know. It's an hack... but it is the shortest way! ;)

Ciao,

Rodolfo
