The current package has the rule
KERNEL=="fb[0-9]*", GOTO="hotplug_driver_loaded"
However, this rule cannot work: At the point where the driver is not
loaded, all you get is a uevent with a MODALIAS property, and without
resolving that modalias, you cannot know what module will be loaded.
Udev cannot set the KERNEL variable before the driver is loaded.
If we don't want to put those modules in load-modules.sh, we can only
put them in our normal blacklist, or blacklist them using a modprobe.d file.
