What about trying to bring up eth1?  If there should only be one  
ethernet device and eth1 now works check /etc/udev.d for two files  
along the lines of:
75-persistent-net-generator.rules
70-persistent-net.rules

The first one creates the second one if it doesn't yet exists and  
records the MAC address and interface number.  If the MAC address for  
an interface changes, it gets assigned to the next available interface  
number.  You can disable this by looking for the device name  
whitelist, something like:
KERNEL!="eth*|ath*|wlan*..........", GOTO="somelabel"

And removing eth* from the list of interfaces the persistent-net rules  
care about.  Newer systems generally having something like:
SUBSYSTEMS=="xen", GOTO="somelabel"
