For creating kernel dynamic modules, needs a module library. If you have no problem while compiling modules in kernel directory [means while kernel building time]. Create a directory in drivers folder, copy the *.c file write the Makefile & Kconfig for that. Once kernel building was done, push that .ko to android fs.
Above procedure is little bit hard, but gives a fruitful result with defined procedure. Regards, Jagan.
