Probably the best workaround for You will be to create two
different pipes and to pass trafic throught the proper one.

ipfw pipe 1 config bw  2Mbit/s queue 25Kbytes
ipfw pipe Z config bw 10Mbit/s queue 75Kbytes

to switch:
 ipfw del XXX;ipfw add XXX pipe 1 ip from xxxx to xxxx
or
 ipfw del XXX;ipfw add XXX pipe Z ip from xxxx to xxxx
