About LCD driver?

Hello,

	My lcd device is via MPC850 parport(because my lcd display screen is small).I write my own driver for it.Here is my do.

	in .config file,I add
	CONFIG_PLCD=y


	in drivers/char/Makefile,I add
	ifeq(($CONFIG_PLCD),y)
		L_OBJS+=plcd.o
	endif


	in driver/char/mem.c,I add
	#ifdef CONFIG_PLCD
		plcd_init();	/*in my plcd.c file*/
	#endif

	At last,i add a new file plcd.c in drivers/char/ .I make zImage again.

I fount plcd.o in drivers/char/.
In my driver plcd_init ,I use printk output some information,
When kernel is run,no information was seen.Writing driver like me is right?
I thank i should see device in /proc/devices,but i could not.I have fill the
each elemnet of struct file_operations.There is noting in boot log,and nothing in /proc/devices.What can i do?
