[LinuxPPS] The final step...

I've just recompiled the kernel to get the ktimer module.

[user at dhcp-187-049 ~]$ cat /sys/class/pps/pps{0,1,2}/assert
0.000000000#0
0.000000000#0
1253803284.704924899#76
[user at dhcp-187-049 ~]$

And from dmesg:
PPS_FETCH: source 0
timeout 0.000000000
PPS_FETCH: source 1
timeout 0.000000000
PPS event at 4294867235
PPS event on source 2 at 1253803219.704925702
capture assert seq #11 for source 2

Which version of LinuxPPS are you referring to? Did you test the
system by using ktimer (the dummy client)?

Ciao,
