Sure looks like its fixed.
Mandriva was ntpd built from sources, as their distro version was way too
old to be used.

Here is my current ntpd.conf, for all the world to see:

# /etc/ntp.conf, configuration for ntpd

driftfile /var/lib/ntp/ntp.drift
statsdir /var/log/ntpstats/

statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable

# If you want to provide time to your local subnet, change the next line.
