Automatically reboot OS X 10.7 after kernel panic? Is there a way to set up Mac OS X (10.7) to automatically reboot after kernel panics?

Yes, it shouldn't kernel panic, I know.  But it does.  I've replaced all the RAM in the system, ran memtest and smart test but it still crashes about once a week.  No 3rd party kernel modules loaded.  It would be almost not annoying if it was automatically rebooting, hence the question.
Open the Energy Saver pane in System Preferences. There's an option to Restart automatically if the computer freezes, if you check that you should get the behaviour you desire.

Note that there are two tabs in Energy Saver—one for when you're on battery and one for when you're running from the power adapter; make sure you set it for each state you want.
