Hi Paul,

Overnight I deleted build/tmp and build/sstate-cache from my workspace
and rebuilt everything.

Then this morning I added the module to the packagegroup and rebuilt the image.
This time the .ko did show up in the rootfs.

So it seems there was some sort of gremlin lurking and now it's gone. I hope
for good.

Thanks for your help
