下面是我去掉lcd驱动的过程：linux3.0.1

1.Make menuconfig

-> Device Drivers                                                  

       ---> Graphics support

                 --->(M)S3C FramebufferSupport (eXtended)

2. -> Device Drivers

       --->Multimedia support  

--->Video capture adapters  

---> (去掉)Samsung TV Driver

3.vi drivers/media/video/samsung/fimc/s3c_fimc_core.c

注释掉//ctrl->open_lcdfifo= s3cfb_enable_local;

         //ctrl->close_lcdfifo = s3cfb_enable_dma;

否则会出现如下错误：

/home/yubo/linux/zImage/3.0.1nolcd/drivers/media/video/samsung/fimc/s3c_fimc_core.c:468:undefined reference to `s3cfb_enable_local'

/home/yubo/linux/zImage/3.0.1nolcd/drivers/media/video/samsung/fimc/s3c_fimc_core.c:468:undefined reference to `s3cfb_enable_dma'

4.vi drivers/video/samsung/Makefile

注释掉#obj-$(CONFIG_FB_S3C_EXT)             += s3cfb.o否则make modules会出错

5. 拷贝drivers/video/cfbcopyarea.ko

       drivers/video/cfbfillrect.ko

       drivers/video/cfbimgblt.ko

1. 搜代码，把引用到s3cfb_enable_local 的驱动也去掉
2. 同样的，搜代码，把引用到s3c_device_tvenc'的驱动去掉，如果去不掉就改代码注释掉引用这个变量的代码
其他同法操作

其中s3cfb_enable_local   s3c_device_tvenc' 因人而异 看编译错在哪就改哪
