Yes the kernel appears to be OK as the PPS is working.  In addition, I had all 
of the symlinks in place before starting ntp.

I get the feeling that it is some kind of permissions issue.  I also had 
permsission issues on Ubuntu with the serial and PPS devices that needed to be 
sorted out.

Next time I boot over to Ubuntu I will test this.  But after having installed 
Ubuntu I can't say that I like it too much.  Mostly a lot of little things 
that I don't like rather than anything big.  But I will see if I can sort out 
this issue before I remove Ubuntu from my machine.  That way it can be 
documented.  

I am running the same kernel verison, 2.6.38-6, on my gentoo box and 
everything works just like it should so it is not something specific to the 
kernel version.
