insmod: Invalid module format error

I have open suse kernel kernel 3.1.0-1.2-desktop on which I used kernel source 3.1.10-1.2 downloaded from kernel.org.

The module gets built.
While loading a kernel module I am getting Invalid module format error with description "first_driver: no symbol version for module_layout"

The following are the logs:
Code:
linux-k2kj:/home/rkpsuse/FirstDriver # insmod first_driver.ko 
insmod: error inserting 'first_driver.ko': -1 Invalid module format

linux-k2kj:/home/rkpsuse/FirstDriver # modinfo first_driver.ko 
filename:       first_driver.ko
description:    My First Driver
author:         Emertxe Info. Tech
license:        GPL
srcversion:     C4CCFC5DA59927FA4A479E6
depends:        
vermagic:       3.1.10-1.2-desktop SMP preempt mod_unload modversions 686 

linux-k2kj:/home/rkpsuse/FirstDriver # uname -r
3.1.0-1.2-desktop

dmesg
first_driver: no symbol version for module_layout

I guess this is because of mismatching kernel versions.

Cannot I use kernel source 3.1.10-1.2-desktop on kernel 3.1.0-1.2-desktop?
Where can I get the kernel source for 3.1.0-1.2-desktop

How to resolve this issue?

CREATE_MODULE(2)					     Linux Programmer's Manual						  CREATE_MODULE(2)

NAME
create_module - create a loadable module entry SYNOPSIS
#include <linux/module.h> caddr_t create_module(const char *name, size_t size); DESCRIPTION
Note: This system call is present only in kernels before Linux 2.6. create_module() attempts to create a loadable module entry and reserve the kernel memory that will be needed to hold the module. This sys- tem call requires privilege. RETURN VALUE
On success, returns the kernel address at which the module will reside. On error -1 is returned and errno is set appropriately. ERRORS
EEXIST A module by that name already exists. EFAULT name is outside the program's accessible address space. EINVAL The requested size is too small even for the module header information. ENOMEM The kernel could not allocate a contiguous block of memory large enough for the module. ENOSYS create_module() is not supported in this version of the kernel (e.g., the kernel is version 2.6 or later). EPERM The caller was not privileged (did not have the CAP_SYS_MODULE capability). VERSIONS
This system call is present on Linux only up until kernel 2.4; it was removed in Linux 2.6. CONFORMING TO
create_module() is Linux-specific. SEE ALSO
delete_module(2), init_module(2), query_module(2) COLOPHON
This page is part of release 3.53 of the Linux man-pages project. A description of the project, and information about reporting bugs, can be found at http://www.kernel.org/doc/man-pages/. Linux 2012-10-18 CREATE_MODULE(2)
