[c-nsp] CBWFQ with bridging on 2821 ISR

My question is regarding CBWFQ on bridged 802.1q subinterfaces.
The setup is as follows:
-- VLAN2 (INTERNET)
CPE FW-- 2821 --
-- VLAN3 (PRIVATE LAN)
1 ethernet port carries 2 vlans, 1 for internet and 1 for a private lan
service to another location. The 2nd ethernet port is connected to the
customer Firewall. For reasons out of my control, the subnet for
Internet and the Private LAN must be the same, say a /24.
I have a Policy-Map for LLQ setup and it must be on the physical
interface, or I get the following error: "CBWFQ : Not supported on
subinterfaces"
Based on the config below with bridging enabled on one vlan and the
customer interface, will the LLQ policy apply to both subinterfaces and
work correctly?
