I don't know if this is documented, but I researched this a while back,
and we can only do outbound CBWFQ+LLQ on this PPPoEoA connection.
Outbound policing does not work there. 
As a workaround: can you try to split policing and queuing into two
policy-maps and apply policing/re-coloring inbound on the LAN interface
and do Queuing/LLQ in the outbound direction on the ATM-PVC? This should
work..
