From the description below that would be because you have to place the
entire hello-mod directory into
meta-intel/meta-jasperforest/recipes-kernel in order for the stock
layer.conf BBFILES variables to include in the bitbake search path.

If you do indeed have have a space in "MACHINE_EXTRA_ RDEPENDS" as in
your message below, that will also lead to failure.

It is still being worked on but it is in HTML form and now part of the yocto-docs/master branch.  It is published at http://www.yoctoproject.org/docs/1.4/kernel-dev/kernel-dev.html.  Feel free to access it and comment.
