Yes it is possible but not recommended. If you really wanted to do it, I would statically assign the wan port on the linksys to an available IP on the Netgear. Ensure you set the Gateway of the linksys to the Netgears Lan IP and lastly make sure you have DNS forwarded on the Linksys so IP's will resolve on the Netgear.
Here are the problems you'll have.
1. You cannot have both routers in the same Subnet, what that means is both Lan IP's have to have a different number, ie... 192.168.0.1 and 192.168.1.1
2. because of 1. Computers on different subnets will not be able to see each other. You will not be able to share printers, folders, music ect..
3. Having 2 802.11x routers in close proximity may cause interference or cause bandwidth degradation.
