Which comes first? Your own script that loads if_re or Xorg being loaded.
The possibility I'm trying to rule out, is that the nvidia module loading it's
agp driver and nvidiactl module, fixes your if_re issues, because they take
up that memory space.
So, to (dis)prove this:
* in /boot/loader.conf and/or kernel config, no mention of if_re
* in /boot/loader.conf load nvidia.ko
* wait till machine boots
* do not start X, instead from root console kldload if_re
* Expected result: failing to load
* start X
* kldload if_re
* Expected result: successful load

Problem with today's modular software: they start with the modules
and never get to the software part.
