Hi Jason,
I just skipped over these links while looking for different
things..

News -- January 20, 2003
Audigy 2 support is now added in the SourceForge EMU10K1 code.
->
http://sourceforge.net/projects/emu10k1
I have no idea if these drivers are synced with the alsa-stuff
but anyway it should be worth a try. Since they come from
Creative directly chances are that they support more features
than alsa's.
