Err, thanks for the vote of confidence, but I'm probably more of a
kernel harasser than hacker. :)

Have you run your Oops output through ksymoops? If you don't, nobody
will pay attention to it. It's not entirely intuitive how it works, so
you might have to fiddle with it a bit. The ksymoops output is
sufficient to avoid having to send System.maps around as it decodes the
stack trace into readable function calls via the System.map.

You can find it on any kernel mirror, err, somewhere or other on it. :)
