reboot(8)'s man page:

      -n      The file system cache is not flushed.  This option  
should proba-
              bly not be used.

      -q      The system is halted or restarted quickly and  
ungracefully, and
              only the flushing of the file system cache is performed  
(if the
              -n option is not specified).  This option should  
probably not be

One or both of those would probably do it.
