With the v2.6.19 Linux kenrel, Roman converted the in-kernel NTP code to
the NTPv4 reference model.

I then modified the SHIFT_PLL value (which defines how stiff NTP's freq
correction is), setting it to 2, and created the second attached image
(2.6.30-pll2.png), comparing against the 2.6.18 numbers in the first
chart.
