I believe the limitation is that you can't do any sort of fancy queuing
(CBWFQ, LLQ, WRED, etc) on a per virtual-access interface basis.
However, this functionality can be done a per VC basis but caveats apply
depending on what platform/image is being used.  Mac, can you let us
know what platform and image you are running?  Also, do you have
multiple PPPoE subs per VC?  If so, per subscriber fancy queuing will be
an issue.

it is possible we now support QoS w/ PPPoE but hopefully someone else
can chime in.  or you may want to contact your Cisco account team.
