Not supported. Wont work. Thats a memory mapped device. Wait until someone writes a driver for it.

(Note: These are NOT the same as a Winmodem which doesnt work for other reasons. Just that mem-mapped modems (95% of all PCI modems) talk to the system in a different way)
Check the hardware compatibility lists.  Then go buy and external modem.  guaranteed to work.
