I think what you mean is that you cant define sub interfaces on the main interface to be able to do inter-vlan routing. This is a function of IOS. You will need to check ur IOS. IP PLUS will be required to be able to do this.
You're not going to be able to do this with the 2509. If my reading is correct, you need a FastEthernet or 10/100 port on the router.The 2509 only has a 10mb port so I don't think ISL will work for you. You second solution sounds similar to the first, a trunk would still have to be in place to pass the VLAN traffic to the router.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
