I simply can't repeat you result.
I used a 3550 and a 2610, both booted with no config. The light on 3550 port-19 turned green even when the ethernet 0/0 on 2610 was in admin shut state. I use straight through cable.
cat-2#sh ip int b
Interface IP-Address OK? Method Status Protocol
Vlan1 unassigned YES NVRAM administratively down down
cat-2#sh ip int brief fastEthernet 0/19
Interface IP-Address OK? Method Status Protocol
FastEthernet0/19 unassigned YES unset up up
cat-2#sh int fa 0/19 status
Port Name Status Vlan Duplex Speed Type
Fa0/19 connected 1 a-half a-10 10/100BaseTX
Router#sh ip int b
Interface IP-Address OK? Method Status Protocol
Ethernet0/0 unassigned YES unset administratively down down
Serial0/0 unassigned YES unset administratively down down
Router#sh run int e 0/0
Building configuration...
Current configuration : 67 bytes
