I'm new to all this, but I kind of expect those devices to be
synchronisable. So I don't understand why there seems to be extra
difficulty doing so with ~identical cards. Does the quality of the
CPU clock have any bearing at all?

(I made a pretty good ntp server by running a Soekris 4501 with a
clock derived from GPS some time ago. PC clocks aren't (weren't)
particularly good: http://www.febo.com/pages/soekris/index.html)

I noticed, while fitting the 9652s, there are two quite large crystals
on board, which may say something about the clock quality.
