Are you telling ALTQ to process _incoming_ packets?
I'm having no problems with ALTQ, using these IPFW rules, for comparison:
# We're not classifying this packet if it's not going out dc0.
add 30000 allow all from any to any not xmit dc0
# NAT'd egress traffic:
add 40000 allow altq natted ip from any to any diverted-output
# locally-generated egress traffic:
# Interactive SSH.
add 51000 allow altq ssh_interactive tcp from any 22 to any iptos lowdelay
add 51500 allow altq ssh_interactive tcp from any to any 22 iptos lowdelay
# TCP ack w/o data, TCP setup, IPTOS_LOWDELAY, DNS
add 52000 allow altq local_fast ip from any to any iptos lowdelay
add 52100 allow altq local_fast tcp from any to any setup
add 52200 allow altq local_fast ip from any to any tcpflags ack tcpdatalen 0
add 52300 allow altq local_fast udp from any to any 53
# Non-interactive SSH.
add 53000 allow altq other_ssh tcp from any 22 to any
add 53500 allow altq other_ssh tcp from any to any 22
add 59000 allow altq local_default ip from any to any
