I don't have any of these; would exim be a usual suspect as well?

That yields syslogd, cron, gdm, XFree86, gnome-pty-helper and lpd. I wouldn't
suspect anyone but syslogd here, right?

How can I do that? I didn't see anything in the syslogd not syslog-ng
manpages.

Would that be via /proc/sys/vm/bdflush? What do the numbers mean?

BTW what would be considered a sane timeout for standby? Does it harm the disk
if I set it to the minimum of 5 seconds and it gets powered down and back up
all the time?
