Slight correction, you would need to use the correct AVPair to apply the policy INBOUND. The one I gave below was for outbound policy. The one to use for inbound is:
cisco-avpair = "ip:sub-qos-policy-in=in-policy-name"
Here is some reading if you wish:
I'd suggest you try the solution from Arie first. It appears much simpler/easier and so is less likely to cause pain for you if you're not worried about doing it for all users.

You could do it by applying a QoS policy
via Cisco-AVPair RADIUS attributes,
You would then
have a policy on the 7200 something like this:
permit ip any any
match access-group name
set ip dscp 0
You might be able to
achieve the same without all the class-map stuff by just using
"class-default" to match and set that to zero, eg:
set ip dscp
You would have to test. We have found result vary depending on
platform and features and so we use the "longer" way as we know it works
Reset the users session and you should be good
to go when they next connect.
Results can be seen using the normal
"show policy-map" command, eg:
LNS#show policy-map int
We are doing this on 7204 running 12.2(33)SRD1
without any problems.
If you want to do some actual queuing/shaping
then you should look to use a parent shaper to shape to the DSL link speed
with a child policy to implement your actual
