One thing the previous Creative cards were always good for was budget music production, using the kX drivers in windows and as10k1 and other tools on Linux. The simple EMU10k1 DSP was easy to program in 10k1 assembly. I still have a Live 5.1 in my system because of that. If the X-fi DSP can be similarly programmed (and if it can do hardware 3D then it probably can), then Creative might become interesting on Linux once again.
