[LinuxPPS] Can't get /dev/pps0 to be a pps source, and a lot of other problems

[MasonCide]

I haven't tried a new linuxpps version for a while, and I almost have the 
2.6.22-rc6 patch working.  I can't quite tell what's wrong.  Here is some 
info:

Debugging pps is enabled in the kernel.

I put this 

SUBSYSTEM=="pps", MODE="0664" GROUP="dialout"

in

/etc/udev/udev.conf

Did 

/etc/init.d/udev restart

Got a clean compile on the:

debian> pps# /usr/src/linux/Documentation/pps

tools, 

Got a clean patch on the NMEA driver with the latest patch, using:

ntp-4.2.4p4

./configure --disable-all-clocks --disablel-parse-clocks --enable-NMEA --enable-LOCAL-CLOCK --enable-linuxcaps

The configure script indicates, for better or worse, I'm not sure, timex.h was 
present, but would not compile

I tried 
timex.h 
from 
/usr/src/linux/asm-i386/timex.h
but no go.

Make finished.

I just want ntpd to work with my GPS on driver 20.

It works perfectly, except for the local GPS on 127.127.20.0, which was 
working with linuxpps for several months.  I strongly encourage Rodolfo and 
the rest of the crew to get this project where it needs to be.  It's almost 
there.  

Thanx for the help.
