Cisco 1841 - 3 ISPs and HWIC-4ESW VLAN Routing

We have a Cisco 1841 with an HWIC-4ESW running IOS 12.3(8)T5.  We have a T1 connected via Ethernet to an ISP router on FE0/0, a DSL connected via Ethernet to an ISP router on FE0/1 and our internal LAN connected to VLAN1/FE0/0/0 on an HWIC-4ESW.  We want to add a third ISP connection (cable via Ethernet to the ISPs router) using the HWIC-4ESW.  I have set up a new VLAN4 on FE0/0/3 to handle this and while I can ping the the ISP's interface from the router and the corresponding VLAN4 HWIC interface on the 1841 from the internal LAN I cannot get traffic from our LAN to route to the VLAN4/cable ISP interface using the same route map approach that works with the T1/DSL connections.

Here are the relevant parts of the config.  Note that we're not doing anything fancy as far as load balancing/sharing/aggregation.  Route maps are used to direct traffic from given machines/subnets out a specified interface.   I understand from Cisco docs that I need to create an SVI and VLAN, but believe I have done so unless I need to create a third VLAN that acts as a common "backbone" for routing among VLAN1, VLAN4 and the FE interfaces.
