I'm running this driver on Fedora 9 x86-64. Gives me some trouble, but 
as big as yours. Most apps work fine. The problems are:
1. Wine, if uses alsa directly, causes sound to be corrupted everywhere 
until driver restart. So I have to use eSound emulation of pulseaudio 
for wine.
2. Only one application at a time can use sound, so I use pulseaudio for 
multiple sound threads mixing.
3. Some games like doom3 can only use alsa and oss, so to redirect them 
to pulseaudio I use alsa-plugins-pulseaudio, but that causes 2-second 
sound delay in those games.
4. About 0.5 second sound delay is present in games that use openal 
(which uses pulseaudio through sdl or esd).
