MSIHardware.com has a file available for download entitled audigyxp.zip @ 14.3mb download size.
The file was uploaded today and FDRSoft reports these drivers sport a version number of 4.12.01.0130-1.20.0030 (as well as these drivers work for all Windows OS) while the original files from CD are version 4.12.01.0125-1.00.0010.
I found nothing on Creative"s pages about these new drivers.
