Sorry, I was a little too fast there. I had overseen that part of your
mail. Thought the 6500 had the command, but I can see it doesn't.

After re-reading the documentation I can see the point: When using "no
mls qos trust" the "mls qos cos 5" should actually catch all packets.

Anyway, an input service-policy should do it.
