That's exactly what you can do with fcron. In crontab you have to
explicitly tell fcron to run cronjobs which should have run during
downtime at bootup. If I recall correctly you have to prefix these
lines with an "@". Otherwise they are handled like in dcron.

The scripts in /etc/cron.hourly etc. are executed at bootup if the
system was down when they should be running. But you can delete or chmod
600 them or just comment the commands out.
