Sort of...

Discovered that mmap() is returning a NULL pointer during the module load. Seems that this comes from the call to ret = vma->vm_file->f_op->mmap(vma->vm_file, vma); in do_mmap_private() in linux-2.6.x/mm/nommu.c

If you comment out the whole if (vma->vm_file) {} block in do_mmap_private(), then the function will make a private copy and modules seem to insert ok.

This seems like a big hack to me - I haven&#39;t worked out why the original isn&#39;t working, but i&#39;m sleepy http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif

Hope this helps someone to work out the real issue...
