You shouldn't need to do that much to the .config and I'm sure that is the problem.

There are a couple of config files in arch/arm/def-configs, empeg-car (Mk1) and empeg-car2 (Mk2/Mk2a). Copy the required one to $KERNEL_ROOT/.config (where $KERNEL_ROOT is the root of your kernel) and then type "make oldconfig". Hit enter for the one and only question that it asks you. Then type "make dep; make clean". You then need to build a compressed image - "make zImage", and you should then be good to go.
