Victor,
I don't suppose you've gotten any resolution? I obviously don't see any here, but perhaps you have come up with something on your own? It seems to me that this issue has stumped the Intel techs, making them get silent. I've been struggling with this Optimus issue as well... I wish I'd have known more details about Intel graphics and Optimus before I bought this laptop. You're right... Nvidia optimus users seem to be screwed.
