I see no reason that you shouldn't be able to do this as your a just essentially turning your wireless router into a wireless access point. You need to run an ethernet cable from one of the ports of your D-Link DI-604 to the... oh wait. I just tried to do a search for a picture of the back of your wireless router... If the back of the router has a modem port that takes an ethernet port, that is where you plug the cord from your D-Link DI-604.
You would then want to some of your connection settings on the Linksys WRT150N-RM to look to the D-Link router for connections. Providing everything goes okay with DHCP settings (you will probably want to set this connection up with a static address in the end) you should be connected, through a different subnet though of course.
If on the other hand the Linksys WRT150N-RM doesn't have an ethernet modem port, things will be a bit trickier. Let us know if you have the ethernet port on the Linksys router or not and I will explain the process in a bit more detail.
