I did check on my recent hardware, the module is not loaded anymore and
everything works fine. On my old Intel machine, I guess uvesafb was
messing with i915, and as you pointed out, "nomodeset" was required.

With your recent patch, uvesafb is not loaded and it works fine out of
the box.

Thanks a lot for all the effort your are investing into this :)
