Perhaps you can combine ipfw/dummynet and pf/ALTQ.
I know for sure that you can use pf and ipfw at the same
time. The filtering is done in a serial way(packets that
are allowed through the first packet filter, go through the
second etc). You can load the modules in any order you like
and this will be the order packets flow through the packet
filters...

Don't know if that's the case with dummynet and ALTQ...

Also, ipfw can "inject" packets to altq. You still have to
use pf for setting up the queues.
