Oh hold on: there's a bug in the patch. After some hacking I do get
output:

Aug  3 11:11:36 keetweej ntpd[15870]: refclock: found PPS source #0 "/dev/ttyS0" on "pps_8250_0"
Aug  3 11:11:36 keetweej ntpd[15870]: refclock_nmea: time_pps_kcbind failed: Operation not supported

BUT: the output is INCORRECT. My GPS is connected to /dev/ttyS1(!).
also the test/ppstest 1 doesn't emit anything at all (apart of the
banners of course).
