Not a real programmer but....

I wonder if adding the following (taken from
shutdown_reset lines in kern_shutdown.c)
DELAY(1000000); 
cpu_reset();

to the following in the cpu_halt(); area would work.

You would have to modify the delay time.

/*
 * If the shutdown was a clean halt, behave
accordingly.
 */
static void
shutdown_halt(void *junk, int howto)
{
  if (howto & RB_HALT) {
     printf("\n");
     printf("The operating system has halted.\n");
     printf("Please press any key to reboot.\n\n");
         switch (cngetc()) {
         case -1:       /* No console, just die */
             cpu_halt();
              /* NOTREACHED */
             default:
                howto &= ~RB_HALT;
                 break;
                }
        }
}
