[alsa-devel] Creative Soundblaster X-Fi

Has anyone worked on developing an open source driver for the sound blaster x-fi cards? I've been sitting on one for about a year (mental note check support *before* buying..) and would love to use it already... Creative has promised drivers but they seem to be in no rush to support Linux. I'd like to try my hand at working on a driver for this, but without any technical specs from creative I wouldn't really know where to begin. Anyone have any suggestions on how to start? Anyone worked on this yet? Am I nuts for even considering this??
