David:

 I've rebuilt the linux kernel with PPS support. So it should be working.
Hmmmm, now I wonder what is going on.. Ugh..   But when it rains it
pours.. Cause now I've uncovered a new issue. Looking at my syslog file,
gpsd is now spiting back this error:

Feb 28 23:08:28 godzilla gpsd[5172]: gpsd: internal error - too many
satellites!
Feb 28 23:09:19 godzilla gpsd[5172]: gpsd: internal error - too many
satellites!
Feb 28 23:12:04 godzilla gpsd[5172]: gpsd: internal error - too many
satellites!
Feb 28 23:14:25 godzilla gpsd[5172]: gpsd: internal error - too many
satellites!
Feb 28 23:17:57 godzilla gpsd[5172]: gpsd: internal error - too many
satellites!


  I tell you, I just can't win.  lol.. I might have to go with a Windows
setup for NTP.. But the anti-microsoft voice inside of me says not to
do it.  lol
