Simple route/gateway forwarding

This is really basic, but since I've never tried it before (and it's not 
working), I want to see if it's possible, one way or another:

customer has a network hooked up to provider A using provider's CPE 
router.  They also have a 2811 doing NAT, which is the default gateway for 
the NAT'd network 192.168.0.0/21.  The 2811 then has a default route to 
the CPE router and a typical "internal" Ethernet on 192.168.7.1 and an 
"external" Ethernet on Provider A's static IPs.

To this, they add a second connection, a business broadband connection 
using a typical broadband router (NetGear, I believe) to provider B. 
They know their provider A static IPs, won't route through provider B's 
network, but certainly the NATed 192.168. network will.  I stick the 
Netgear on the same Ether as the 2811's internal interface and give it 
192.168.7.10.  All workstations use a default gateway of 192.168.7.1.  The 
idea is to be able to switch them over to 192.168.7.10 without having to 
change their settings, by just re-routing some networks on the Cisco to 
provider B.  I tried this as a test:

ip route 192.168.3.240 255.255.255.255 192.168.7.10

Similar to a ppp /32 route.  However, all traffic from 192.168.3.240 still 
goes out the default route to provider A via the default route.  Is there 
a way to make this work without subnetting 192.168.3.0 and putting aliases 
of it on one or both routers?
