No hci0 in 2.6.31-rc4 with the imac 9,1

The macbook is showing a device when issuing the command hciconfig but with the imac 9,1
nothing happens. Is there a patch that has been created for the imac 9,1 (device number added to drviers/bluetooth/*) or is this something I need to figure out, if so How difficult?
