编译armlinux驱动时不要用错了linux 内核版本

问题描述：
－－我在交叉编译arm板的demo驱动程序的时候，出现的问题和下面的很像。结果根据本文最后一行的提示，发现是用错了linux 内核版本:arm板上用的是arm-linux-2410,我的demo驱动是板子自带的。后来用了redhat9的kernel文件来编译，不通过。老是报找不到文件。
其实主要是有两种解决办法：1.直接用arm-linux-2410内核，原驱动就是在此基础上建的，include 的好多，就是由指向纯净内核的asm-arm的asm链接和指向asm-arm/proc/的proc链接组成的。一个redhat9的内核是不是这样被改装成arm-linux的内核？（其实linux纯净内核本身是包含了一些arm的代码的）。
我的无线网卡为asus　wl-167g　驱动是官方网站下的，已在ＰＣ机的linux系统上能正常工作．系统是VMware 虚拟机上的redhat 9.0, 内核为2.4.20-8.
现在想把它交叉编译,使它能在ARM板上使用．安装了arm-linux-gcc -3.2.3 环境．我修改了Makefile,把编译器修改成了arm-linux-gcc，
make时出现问题

好象是汇编的错误，问题可能在那里啊？请高手指点！
Makefile 内容如下：
# Comment/uncomment the following line to enable/disable debugging

CC := arm-linux-gcc

include ./config.mk

WFLAGS := -Wall -Wstrict-prototypes -Wno-trigraphs

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊网友提示：
dx, cx,edx 这些都是X86(pc)上的寄存器，你include/asm链接的目录是错误的，你连接的是X86的头文件目录，在ARM平台应该链接ARM平台目录，你应该使用交叉编译ARM的LINUX内核目录树，而不是X86的
