Of course I did, Simon, what did you expect? :P
Here you are:
http://www.winehq.org/pipermail/wine-devel/2014-February/103108.html
It contains a description of the DInput effect file format (.ffe), a
working Python script to load these files and dump their contents, as
well as a bunch of example files and tests/results.
The FFE file format is binary RIFF, if you're interested.

But I prefer not to include such things in the Linux kernel, I believe
this is the task of the userspace application.
I'm planning to implement this function into Wine, but maybe SDL would
benefit from similar functionality too (using an open file-format
instead, of course)?
Anyway, this is off-topic.
