You could try using a udev rule.



For example, you can create a file /etc/udev/rules.d/99-disable-eth.rules with the following content:



ACTION=="add", SUBSYSTEM=="net", SUBSYSTEMS=="pci", RUN+="/bin/sh -c 'echo 1 >/sys/bus/pci/devices/0000:04:00.0/remove'"


Feel free to customize it further to add more specific items, like the vendor attribute, the name of the interface, etc.



Take a look at http://www.reactivated.net/writing_udev_rules.html for more examples and additional information on writing udev rules.
