Correct! As said before: Linux 2.6 still has the old NTP kernel code. As long as there is no nanosecond clock for Linux 2.6, you'll have to wait. (I had implemented a new nanosecond clock for Linux 2.4, but it never made it into the mainstream kernel. I won't do that again, but let the others (who know better) do it). For 2.6 you only get the PPS API's essential parts (plus the parallel port support).
