在网上搜索相关信息，发现了T-Bagwell去年的帖子，信息一样啊，怎么解决的？谢谢！
Makefile：
------------------------------------------------------------------------
CROSS_COMPILE=arm-linux-
ARCH:=arm
CC:=$(CROSS_COMPILE)gcc
LD:=$(CROSS_COMPILE)ld
obj-m = led_driver.o
module-objs = led_driver.o

KDIR = /home/dingf/linux-2.6.36/
PWD = $(shell pwd)
default:
$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules
clean:
rm -rf  *.o *.ko *~

搞定了：命令行上要把arch 和cross_compile指定
我得kernel就是这么编译的

[root@vmpc led_driver]# make ARCH=arm CROSS_COMPILE=arm-linux-
make -C /home/dingf/linux-2.6.36/ SUBDIRS=/home/dingf/led_driver modules
make[1]: Entering directory `/home/dingf/linux-2.6.36'
  CC [M]  /home/dingf/led_driver/led_driver.o
  Building modules, stage 2.
  MODPOST 1 modules
  CC    /home/dingf/led_driver/led_driver.mod.o
  LD [M]  /home/dingf/led_driver/led_driver.ko
make[1]: Leaving directory `/home/dingf/linux-2.6.36'
[root@vmpc led_driver]#
