In step 4, why are you coping the .config file into tmp/work/edison-poky-linux/linux-yocto/3.10.17-r0/linux/arch/x86/configs/i386_edison_defconfig?
I also noticed that after step 3 (if we skip step 4) you didn't modify <edison-src>/meta-intel-edison/meta-intel-edison-distro/recipes-core/images/edison-image.bb to add your module to the recipe. You can add the line IMAGE_INSTALL += "package-name" to add the package to the build of Edison’s image. After adding that line you should be able to build the image with the driver included. Also, make sure that you are not missing any dependency for the driver otherwise it won't work. You can check the dependencies of a particular package in menuconfig.
