Aren't Cisco and Linksys the same thing? ;-)

I'm doing the VLAN routing with an Ubuntu server with 4 network cards (one for each VLAN). I turned on IP forwarding to route the traffic between the subnets. In this case, each VLAN is also an IP subnet. I suppose that is cheating a bit. There probably is some geeky way to trunk the VLANs over to the Linux box on one cable instead of 4 and then have Linux do the routing between VLANs. I didn't go that route. In my case, Linux doesn't even know about the VLANs. It just knows that each card is in a different subnet and does IP forwarding accordingly.

I'm using Shorewall to control the flow of traffic between the subnets. I've also setup a bunch of static routes on the router so that traffic can get to the firewall and back.

Routing performance is remarkably good!

Cisco owns Linksys, but they are definitely different products.

It seems like Cisco releases a feature in their Linksys line as a testbed for the feature though.

VLANs are always different subnets, with the exception of Private VLANs, but that is well beyond the scop here.
