Why dont you just dedicate a vlan for each inter-vrf  connection like so:

int fa0/0.10
encap do 10
ip addr 10.10.10.1 255.255.255.0
int fa0/1.10
encap do 10
ip vrf fo X
ip addr 10.10.10.2 255.255.255.0

Dont need anything "fancy" in the switch.

You can actually build this with tunnels and loopbacks. You can also use 
a crossover cable between two fastethernets on the router without a switch.
