According to the block diagram in the User's Manual the Xilinx plays a 
major role. The FPGA provides even more functions than in Juli.

Without some information from the manufacturer (even if under NDA) the 
driver will be rather difficult to write. The FPGA is controlled by 
Envy's GPIOs and their signals would have to be electrically analyzed 
under Windows driver - a pretty complicated task. It is very different 
from a regular card with well-documented codecs only where you just need 
to trace codec pins to corresponding GPIOs.

Pavel.
