Networking - multiple nics not setting up

Hi folks,

I have a networking problem with a fresh install/upgrade of 
feisty to gutsy.

The box in question has three nics but they aren't setting up
correctly. All are correctly connected to a switch and the 
leds on the card are lit. I'm using static IPs and there is no 
wireless connection either. There seems to be some sort of auto 
configuration mechanism at work that is creating interfaces
I don't want/need and overriding the one I do want even 
creating a fictitious network.

At first I could only get one card detected - the one I set 
up manually - IP, netmask, GW, static address. The other cards 
didn't even show up. Later I began playing with 
/etc/network/interfaces and one of the cards kept being 
assigned an incorrect FF:FF:FF:FF:FF:FF mac address while the 
other seemed ok.

The thing is there should be an eth1 interface set up.
Instead I get two virtual interfaces eth3 and eth3:avah.
The basic information for eth3 is correct but I don't 
want the eth3:avah interface or the 169.x.x.x network. 
It's the first time I've seen it. Is it dhcp, wireless, 
or IPv6? More importantly, how do I get rid of it. You 
can see what I want from the /etc/network/interfaces file 
below and the output from ifconfig -a and route -n.

All advice appreciated.
