SupremeXF X-Fi with x-fi fatal1ty front audio panel connector?

Just bought a Crosshair III mainboard, which comes with it's own SupremeXF X-fi soundcard. I already have the x-fi fatal1ty with the font panel audio conectors.
There are two other PCi-x1 sockets on the board so I would be able to use the existing sound gear if I need to. However, the SupremeXF has connectors enabling it to be connected to font panel audio connectors.
Does anyone know for certain if the Fatal1tys front panel is fully compatible with the SupremeXF.
