Attached, you will find :

 * mykmod-1.0.tar.bz2, the source code of an hello world like kernel
   module ;

 * kmod-example.patch, which adds support for compiling this kernel
   module into the Buildroot package infrastructure

Do not hesitate to get back to the mailing list if you have any issues
getting this to work or need additional details.

Best regards,

Thomas
