Sorry, forgot to mention that this is indeed i386...

Applied the patch and it looks as though cron is behaving now

Before
Jun 30 18:58:59 gw /usr/sbin/cron[25911]: (root) CMD (/usr/libexec/atrun)
Jun 30 18:58:59 gw /usr/sbin/cron[25912]: (operator) CMD
(/usr/libexec/save-entropy)

After
Jun 30 19:10:00 gw /usr/sbin/cron[26085]: (root) CMD (/usr/libexec/atrun)
Jun 30 19:11:00 gw /usr/sbin/cron[26097]: (operator) CMD
(/usr/libexec/save-entropy)

Hourly will take a while...
