Prashanth is right, both linecards will operate at the speed indicated. Beware that the linecards will have some oversubscription (meaning that not all ports in a port group will be able to use their max speed at the same time)
Any given port will communicate with any other given port on the same switch at the maximum speed that _both_ can attain. A 2Gb port will not magically start working at 4Gb just because it's sending data to a device attached to a 4Gb port.
This holds true for as long as the link between the linecard and the crossbar is not saturated. This is what oversubscription in this case means: for a 4:1 oversubscription only a quarter of the ports can communicate with the backend at their maximum speed. While this is oversimplified, it's a good general rule of thumb.
As for your particular case: the backend of the switch will not force your 4Gb linecards to become 2Gb because there are earlier generation linecards present. You will however not be able to run all of your 4Gb port at an actual sustained data rate of 4Gb at the same time, but this is by design.
The unmanaged mode is also known as Network only switching, which is introduced in Brazos release. It adds the flexibility for customer to use only network automation for service appliance.
