Rebuilding Gumstix kernel

I've been trying to enable usb camera support for a while and have been following the instructions available at (). Did the make ARCH=arm menuconfig etc. but still was having trouble getting the kernel objects (.ko) files be included in the build. Finally came across the following page (while trying to enable rootfs over nfs) that seems to explain the mystery:

http://docwiki.gumstix.org/index.php/Recompiling_the_Linux_Kernel

During this step:

make ARCH=arm menuconfig

(make your changes to the kernel here and save the config file on exit)

If you want to keep these change in this buildroot 

THIS WAS THE MISSING LINK!

cp .config ../../target/device/Gumstix/basix-connex/linux.config

Now build the NFS enabled kernel

make ARCH=arm clean

rm build_arm_nofpu/root/boot/uImage

from your gumstix-buildroot

cd 
make
