Me neither. 

I too have a 4965 and its channels appear fine under the world
regulatory domain. Specifically:

$ iw reg get
country 00:
	(2402 - 2472 @ 40), (3, 20)
	(2457 - 2482 @ 20), (3, 20), PASSIVE-SCAN, NO-IBSS

	(5170 - 5250 @ 40), (3, 20), PASSIVE-SCAN, NO-IBSS
	(5735 - 5835 @ 40), (3, 20), PASSIVE-SCAN, NO-IBSS

Hopefully Luis can see why your channels are not showing up correctly.
