Asbjorn,
As I stated in the email:
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat4000/relnotes/ol_5184.htm

Cisco Catalyst 4500 Series Supervisor Engine V-10GE Uplink Enhancement for simultaneous use of 10-Gigabit Ethernet and the Gigabit Ethernet SFP interfaces. (The Catalyst 4510R requires optional configuration. See the "Configuring Interfaces" chapter.) 

- --------------------------------------------------------------------------------
Note On a Catalyst 4510R series switch, if you enable both the 10-Gigabit Ethernet and the Gigabit Ethernet SFP uplink ports, you must re-boot the switch. On the Catalyst 4503, 4506, and 4507R series switches, this capability is automatically enabled. 
- --------------------------------------------------------------------------------


The above from the release notes states that they are on by default on all chassis except the 4510R. On the 4510R they must be configured manually, and it requires a reboot.
