Once you've added the stubs for the extension (as you have done), you
still need to code up specific support for that extension in the
specific SPU's. Some SPU's will need more work than others, and the
_special files are provided to allow the SPU to derive it's own
function.

But you need to carefully add support to all the SPU's in your chain to
ensure the extension you want to add will be supported.
