It is spread around in a number of documents and it is also not entirely clear how much of the 6500 architecture you are already familiar with.
In short -
classic line cards connect to the 32Gbps shared bus only
Fabric enabled cards can connect to the switch fabric and to the 32Gbps shared bus
Fabric only cards can only connect to the switch fabric.
Fabric enabled and fabric only have different connectors to the switch fabric ie. number of connections and speed of connections eg.
WS-X6548-GE-TX is fabric enabled with 1 x 8Gbps connection to the switch fabric
WS-X6748-GE-TX is a fabric only card with 2 x 20Gbps connections to the switch fabric
Probably best to start with the architecture paper which explains the different type of modules/connections within the 6500 -
