Hi Youri,

what you are trying to achieve is not very easy, considering that some of the Netkit components are, unfortunately yet undoubtedly, a bit outdated, and this applies also to the kernel.

It is a good choice to build your custom module by relying on an already installed kernel source tree but, as you see, you may encounter two mismatches:
- on the kernel release
- on the kernel target architecture (supposedly the host's)

Instead, I suggest you to download the correct version of the kernel sources from https://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.26.tar.xz, recompile it for the User Mode architecture (see the instructions at http://wiki.netkit.org/download/netkit-kernel/README), then add your custom module to this build.
