Why don't you just put every port on the 2950 in a different VLAN
("switchport access vlan X"), then make the connection between the 7206
and the 2950 a dot1q trunk. Then just create a subinterface on the 7200
for each vlan, like

interface FastEthernet0/0.101
  encapsulation dot1q 101
  ip address ....
!
... etc

Hint. Avoid VLAN1. For the 2950, use e.g. VLAN101 - VLAN124 for ports
1-24.
