[PATCH] Fix Macbook Addon to work after resume

[Martin Szulecki]

I was finally able to get suspend to ram working on my Macbook
(non-Pro).

In order to make it work (it appears this is required on latest Xorg and
intel drivers) I had to change the currently set quirk from
"vbestate_restore" (causing system freeze on resume) to
"vbemode_restore" (flawless).

However, without restoring the state, it appears some registers come up
reset to zero which makes the addon refuse to work.

I attached a tiny patch to fix the addon to work even after a
suspend/resume.

If anyone else is able to verify that "vbemode_restore" is enough on the
Macbook it might be good to change the appropriate fdi file aswell?
