I'm not sure what you are asking. You can either

      * Pass arguments to your existing kernel on boot (through the grub
        command line), or pass them to modules when they load:
      * You can change some settings of your existing kernel at runtime
        through /sys and /proc/sys (I didn't find useful online docs for
        that right now)
      * You can recompile your kernel and change lots of things (but
        then it is not your "existing" kernel anymore)
