2 eth-interfaces bound to same physical nic

I have just installed a new system (lenny stable) and have 2 nics one onboard intel 10/100 and a second Broadcom bcm5705 card. I have set networking in /etc/network/interfaces to the following.

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback

allow-hotplug eth0 (this shows as the Broadcom card in dmesg)
iface eth0 inet static
address 10.10.1.253
netmask 255.255.255.0
broadcast 10.10.1.255
network 10.10.1.0
gateway 10.10.1.1


allow-hotplug eth1 (this shows as the 10/100 card in dmesg)
iface eth1 inet static
address 10.10.1.252
netmask 255.255.255.0
broadcast 10.10.1.255
network 10.10.1.0
gateway 10.10.1.1

The problem is if I connect to either the 253 or 252 address they both connect through the Broadcom card and nothing will connect to the on board. Is there some sort of binding problem?

What is 10.10.1.1 (physically) and which card is it connected to?

You might try replacing "allow-hotplug" with "auto" - in my experience the behaviour of hotplug can be unpredictable if using more than 1 nic.
