OK, SCRATCH THE PREVIOUS COMPLAINT.
I have restarted linux-2.6.27-rc4-PPS, with the newly recompiled 
ppsldisc, and ntpd, and ppsapitest8 (my version of ppstest), and 
EVERYTHING seems to be working fine.

No idea what caused the problem when I did this an hour ago.
My guess might be that an old ppsldisc was hung running, but who knows.

More info when Ive run long enough to see how things look.
