cat /var/log/messages.log | grep "Kernel command line"
..would likely do the job for you. The only time that phrase is issued is during boot. NOTE - you can likely grep the syslog file too, it should contain the similar information. Though at a glance, it looks like you already have identified enough info yourself there, to determine when it rebooted.. No?
