Strange, it seems to work now - occasionally.
See http://amedee.be/cgi-bin/smokeping.cgi to see what I mean. Notice the
large gaps.

Indeed, when I do /etc/init.d/smokeping restart, it says

root at debian31lamp:~# /etc/init.d/smokeping restart
Restarting smokeping: ### fping seems to report in 1 milliseconds
Note: logging to syslog as local0/info.
Daemonizing /usr/sbin/smokeping ...
smokeping.

root at debian31lamp:~# /usr/sbin/fping -C 1 localhost
localhost : [0], 84 bytes, 0.13 ms (0.13 avg, 0% loss)

localhost : 0.13

--> Yes.

These versions should be OK, right?

This is /etc/smokeping/config:
