have a look at /etc/udev/rules.d/70-persistent-net.rules.  This file
tries to make sure that network adapters are always named in the same
way in whatever order they are started.  The problem comes when you replace a 
network adapter.  To get the system to accept the new adapter as the original 
simply remove this file and reboot.  Udev will then recreate the file using  
the now installed adapters.
