I've had the Dragon apart since changing my Sirius receivers and have been tinkering with adding a new sound system and a Nokia car kit. During all this the driver's seat has been in the back. While I had it out to do some measuring I noticed something interesting on the bottom of the seat pan. It appears to be a grille and mounting slots for a standard 4" fan, much like you'd find on a computer power supply and many other common cooling functions. The seat foam is within a 1/4" of the grille so it's unlikely useful as our seat is configured, but perhaps there was some interesting Recaro option with the line of seats we share the pan with.

Take a look at the pics and share your theories...
