Does this mean one has to add that command line option unless i915 is already loaded on boot (or built-in)? I can easily see i915 not being in the initrd for some reason but being loaded only after the root filesystem is mounted. And that in turn may take a while if the user has to enter a password for disk encryption. If the user has to add a command line option in such cases I think that would be very inconvenient.
