    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    I'm pretty sure the problem here is that you are using "old" style compilation. The thread where this appears to have come from is pretty old and refers to a 2.4 kernel - not so long ago, I found that making my own module wasn't working as the book I was reading. Reason: Book talked about 2.4 kernel, and I had a 2.6.13 or so kernel. 2.6 has a different kernel format.

    There are a few different solutions - in my case, I choose to just add my module to the normal kernel build.

    Try searching for some info based on 2.6 kernel.
