On ARM, arch/arm/boot/Image is the raw uncompressed version of the kernel. You can try to load it and jump to the beginning of it. You can turn it into an uImage by calling mkimage on it. However, as suggested by Jean-Christophe, you should really try LZO. It is a very good trade-off between kernel size and decompression time. Remember that using an uncompressed kernel means that you have a *lot* more data to load from flash to RAM, which allows take time. Usually LZO is a great compromise here.
