I've also run into the problem recently on 9-CURRENT (last synced on 11/13/2009).  My configuration looks like:

# Configure traffic shaping.
$fw pipe 10 config bw 950Kbit/s
$fw queue 10 config pipe 10 weight 100
$fw queue 20 config pipe 10 weight 1

# Shape traffic to avoid ACK starvation when our upload is saturated.
$fw add 6100 queue 10 tcp from any to any tcpflags ack iplen 0-80 out via $oif
$fw add 6110 queue 10 udp from any to any iplen 0-80 out via $oif
$fw add 6120 queue 20 tcp from any to any \{ not tcpflags ack or not iplen 0-80 \} out via $oif
$fw add 6130 queue 20 udp from any to any not iplen 0-80 out via $oif

The output of the sysctl elements are:

Thanks for the help.
