I have linux installed in vmware which is not connected to net and so I have to manually download the source.

---------- Post updated 02-03-12 at 01:03 PM ---------- Previous update was 02-02-12 at 08:56 PM ----------

Now I have open suse kernel kernel 3.1.0-1.2-desktop and its kernel source.

Again 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/Emertxe/CourseTemplates/FirstDriver # insmod first_driver.ko 
insmod: error inserting 'first_driver.ko': -1 Invalid module format

linux-k2kj:/home/rkpsuse/Emertxe/CourseTemplates/FirstDriver # modinfo first_driver.ko 
filename:       first_driver.ko
description:    My First Driver
author:         Emertxe Info. Tech
license:        GPL
srcversion:     C4CCFC5DA59927FA4A479E6
depends:        
vermagic:       3.1.0-1.2-desktop SMP preempt mod_unload modversions 686 

linux-k2kj:/home/rkpsuse/Emertxe/CourseTemplates/FirstDriver # dmesg | tail
[ 8797.391736] first_driver: no symbol version for module_layout

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

FYI I have compiled the kernel as follows:
Make mrprpoper
make menuconfig
Make
Make modules
Make modules_install
Make install

Am I missing something?
How to resolve this issue?

NAME
insmod - Simple program to insert a module into the Linux Kernel SYNOPSIS
insmod [filename] [module options...] DESCRIPTION
insmod is a trivial program to insert a module into the kernel. Most users will want to use modprobe(8) instead, which is more clever and can handle module dependencies. Only the most general of error messages are reported: as the work of trying to link the module is now done inside the kernel, the dmesg usually gives more information about errors. COPYRIGHT
