You probably want to kill X off just before the final power down. A few
boxes get a bit confuddled if the BIOS video mode isn't reset (I've got one
here which objects if you do a hard reboot from inside an X window) - its
fine after a real reset or if you got text mode first

Hard bit seems to me being sure the old X server is dead dead dead before
the new one begins. Other problem is that X takes longer to start on some
boxes than poweroff to finish....
