It seems Creative have had a rethink and will be offering the Alchemy drivers for the Audigy cards free of charge.. If you have already paid for the driver you may be in line for a refund... Go here to register:
ALchemy for Audigy

On a more personal note, I think this great. Users should not be penalised for using a different os and the original action by Creative was a rather sneaky one. At least this goes some way to puttiing Creative in a better light.
When the link becomes available for the free set of drivers I'll post..
