that defies my understanding of things so I struggle to believe it.
what is output of say...
ls -l /var/log/lpr
?

You might want to see what is actually in those files...
(/etc/cron.hourly/*, etc.) and potentially edit or remove them as
useful. I suspect the ones that are making you crazy are in the
cron.hourly
Clearly the 'promisc_check.sh' is in the hourly and that would seem to
be a safety check from your distro and it is reporting to syslog which
actually makes a lot of sense and I would probably just leave it alone
(i.e. keep running the 'promiscuity check' every hour but that's just
me)
The permissions check are probably part of logrotate and it's possible
that some of the logrotate functions aren't setting the permissions
right when it creates/rotates logs (note the 4:02 time) so you might
want to check /etc/logrotate.d/* stuff but again, I think this is the
kind of thing that your particular distribution should be aware of and
make fixes for unless this is because you already 'fixed'.
In summary, I would want to fix the permissions issues being reported
but I'd probably leave the safety checks alone.
