Seems to me your question relates to fundamental switch design issues.
Switches trade options for speed by implementing QoS in hardware. Most
Catalysts do not allow outbound policy-maps at all. QoS decisions are
made centrally as the frame passes through the switch. Two good sources
for study would include:
Cisco Catalyst Qos by Flannagan, Froom and Turec
or
End-to-End QoS Network Design by Szigeti and Hattingh
You might also check out Cisco LAN Switching Fundamentals by Barnes and
Sakandar. It has some very good sections on Catalyst architecture.
I am sure one of the CAT gurus on the list can provide more detail.
