linux内核LCD驱动加载问题

[wowooooooooooo]

我编写lcd驱动后，加载了cfbcopyarea.ko cfbimgblt.ko cfbfillrect.ko 三个模块，用lsmod命令显示模块也加载成功，如下
[root@haiyang /]# lsmod
cfbfillrect 3544 0 - Live 0xbf006000
cfbimgblt 2556 0 - Live 0xbf003000
cfbcopyarea 3020 0 - Live 0xbf000000

但是为什么加载lcd驱动后会显示下面的问题呢？谢谢
[root@haiyang /]# insmod lib/modules/2.6.31/lcd.ko
lcd: no symbol version for cfb_copyarea
lcd: Unknown symbol cfb_copyarea
lcd: no symbol version for cfb_imageblit
lcd: Unknown symbol cfb_imageblit
lcd: no symbol version for cfb_fillrect
lcd: Unknown symbol cfb_fillrect
insmod: can't insert 'lib/modules/2.6.31/lcd.ko': unknown symbol in module or invalid parameter
