That could very well be the problem. I complied a PPS-enabled kernel
with all the PPS options built in, so I ran menuconfig again and
deselected the KTIMER option. It will take about a day and a half to
recompile (it's a Thinkpad circa 2000) and then I'll try it again. I
did have a pps0 showing up at boot without having to run ldattach.
