#include <linux/module.h> ?

Did it fail to compile for you?  The 3.2 version included linux/export.h
which didn't exist, and that failed the compile for me. I removed it an
it compiled fine. But perhaps I should have replaced it with module.h.
I'll look into it.

I saw compiler warning go zinging by, stopped the build and added the
include.  Trying to use the posted patches doesn't work without digging
out the signature damage, so it was easier to make my own.. and I too
just spanked the non-existent include :)
