Can I set an Audigy's EAX settings on Linux?

I have a creative audigy sound card that works real nice in XP, openSuSE 10, and Ubuntu HH 8.04. The biggest drawback is that i cannot access the EAX settings from either distro. The sound plays fine, and i can tweak all the S/PDIF and og volumes with alsamixer, but I can't find any way to turn the CMSS or other enhancements on or off.
