[alsa-devel] X-FI Datasheets Question

I remember about a year ago James Dutton received the datasheets from creative for the X-FI. I was just wondering if he ever attempted to write a driver? I am just curious because now we have the source driver from creative, but I am hoping for some more features like HWMIX and Wavetable support for the X-FI. Any chance of these features in the future?
