In the 6509, all eight linecards can attach to the 720 Gbps fabric.
On the 6513, this seems to be true for only five out of 12 slots.

At least that's my reading of the White Paper on the three 10GbE
linecards.  For the new aCEF720 and dCEF720 10GbE cards, it says:

    Slot requirements:
    
    Can occupy any slot in any Cisco Catalyst 6503, 6506, 6509, 6509
    NEB, or 6509-NEB-A chassis, or any Cisco 7603, 7606, 7609, or
    OSR-7609 chassis; Can only occupy slots 9 through 13 in a Cisco
    Catalyst 6513 or 7613 chassis.
