insmod : Invalid module format

[scanty]

hi all,
i am trying to get a simple module working

hello.c
#include <linux/init.h>
#include <linux/module.h>
MODULE_LICENSE("Dual BSD/GPL");
static int hello_init(void)
{
printk(KERN_ALERT "Hello, world\n");
return 0;
}
static void hello_exit(void)
{
printk(KERN_ALERT "Goodbye, cruel world\n");
}
module_init(hello_init);
module_exit(hello_exit);

Makefile
obj-m +=hello.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules


the module is created but not inserted.
I m using Ununtu 9.10 with kernel 2.6.33-020633-generic downloaded as deb file from ubuntu site .

Plzz help..

So, where in your make file are you installing the kernel module? Have you tried to install it manually?

i have posted the make file in the first post.
i tried to install kernel manually but finally got this error
