Have you tried implementing Modular QoS CLI (MQC) using service policies? I haven't worked on the 7500 platform but we have successfully applied QoS for VoIP on subinterfaces on the 7200 series routers.
It should be noted that on sub-interfaces, you need a parent service policy to shape traffic to a particular level and then a child service policy which will carry out the actual QoS markings/prioritizations within the shaped allowance.

They are connected to L2 switch and trunked into a 7500 router via VLAN. This has worked fine so far with the use of rate-limit on the sub-interface. Most customers have 5~10mbps. However, we are increasingly needing QoS so VoIP traffic does not drop when data traffic bursts. Only work around I know how to do is to give separate rate-limit based on IP address since most of the time VoIP has separate gateway on the customer side than the data firewall. Classification of the traffic is not a problem. The issue is, how do you give VoIP traffic priority over data traffic on a Ethernet sub-interface? Is there a good way to implement this on a 7500? If not, what Cisco hardware will work? We are on a tight budget and the number of clients are small. (dozen or so) Would going with L3 switch be better? If so, what model?
