I don't think Ollivier is doing PPP/hardpps() yet, at least I have not
given him the semi-magic code needed for it :-)

I wouldn't recommend trying it either, he is bound to have a >1
msec jitter on the DCF77 waves at his place, and that is a lousy
diet for hardpps().

PS: I have updated my rover page, you can see the performance of my
machine with the nanokernel-PLL patch, 4.92c and a UT+ Oncore on

	http://phk.freebsd.dk/rover.html

(This isn't using hardpps() either!)
