Unfortunately, I won't be able to test this, as I don't have access to the computer anymore (it is now with my ex-partner). If, on the other hand, I could test it with a computer that has an hybrid Intel Sandybridge + an AMD Radeon board (I sincerely don't have any clue on how the switching between the cards happen or if I am only using one and not the other), then I can do whatever you want me to. On a second note, it does not seem to have been picked up by any of the released trees that I have seen so far... Should I probe someone to get this included, at least downstream?
