The generic BSD kernel does not enable PPS support by default.  You must 
recompile to enable PPS.


The page you quoted says the following in the section "System software 
customization" (about 45% down the page in the Software section):

System software customisation

Need to add one line to the Kernel configuration:

     options PPS_SYNC

and recompile the Kernel.  On my 133MHz/48MB system this can take 
several hours.  Note the configuration suggestions below before you 
recompile the kernel.
