Run  startup script that uses at to schedule a reboot. Call this script
reboot_later and put it in your startup sequence:

   #!/bin/sh
   /root/reboot_in_four_hours &

Call this script reboot_in_four_hours and put it in /root

   #!/bin/sh
   sleep 14400
   reboot

Alternatively, call this script reboot_later and put it in your startup
sequence:

   #!/bin/sh
   echo reboot | at now + 4 hours 

Note: All the above is totally untested!
