I ran into this recently.
It does that because udev maintains a list of network devices
listed by MAC address in a file somewhere -- I thought it was
obvious in /etc/udev, but I can't seem to find it on my system
here -- maybe it's different in lenny?
Anyways, it certainly did this in "etch".
When you transplant a system image including this file onto new
hardware, udev notices the difference in MAC address, and gives the
interfaces it finds names that won't conflict with the MAC address
assigned for eth0.
Obviously this system is designed to maintain name integrity
when you drop a new network card into an existing system, but
it does have unexpected behavior for transplanted images.
