Reverted your patch then changed line 1011 of init.c to _exit(97):

warning("single user shell terminated.");
sleep(STALL_TIMEOUT);
- _exit(0);
+ _exit(97);
} else {
warning("single user shell terminated, restarting");
return (state_func_t) single_user;
...and got a panic that showed "exit 97": http://imgur.com/xonPwxR
I think that kern_reboot() is not being called somehow.
kern_reboot() is the only place rebooting = 1; is executed.
"init died (signal 0, exit 97)
panic: Going nowhere without my init!"
can only happen if rebooting = 0 in kern_exit.c exit1().
Another tell that kern_reboot() has not been called is "cpuid = 3"
because the first thing kern_reboot() does is bind to CPU 0.
Why is kern_reboot() being skipped? I have no idea.
Anything more I can do to help? Do you want a core dump?
