auto QoS in physical Interfaces Switch 4507R+E

I'd like to take a doubt, I'm dealing with a customer that has a Core Cisco 4507R + E with 2 Sup WS-X45-SUP7-E and WS-X4748 line cards 3-RJ45-E with IOS version below:

He is implementing ToIP. The topology is structured in the collapsed model where switches etherchannel uplinks have access to 2Gb Core. 
On all access switches the "auto qos trust" for uplinks and the "auto qos trust cisco-phone" to access ports was implemented. In Core would have to disassemble the PortChannel, apply auto qos trust in the PortChannel interfaces and ride again. 
The doubt is that setting the 4507R + E accepts the QoS on the doors of the Port Channel? 

As this Release Notes 

box in Release 3.2.3 does not support QoS on physical ports that composes the PortChannel.
