The wait is finally over. All Tux64-pals can now use Sound Blaster X-Fi series cards and the Auzen X-Fi Prelude on 64-bit Linux. Here's a link to the download page. Please also note, that it's a beta driver and could be very buggy. It supports 64-bit linux and is a source tarball, meaning that you have to compile it. There however is no driver for 32-bit Linux, my support email to Creative has no reply and they seem tight-lipped about it. But since most X-Fi users do have processors with either AMD64 or EM64T, most users won't have a problem. 32bit only users, sorry for the disappointment.
