I also have the same problem, have you managed to figure anything out?
I've tried everything I can think of, except booting it in fireware-mode and do something from there.
Whatever I try to do it always ends up right after "vmci: Module initialized"
Hei, just to let you know. I gave up and delivered my machine to mac repair. It turned out that a module error was the cause of my problems. They have since replaced the defective part and my machine works like a dream. No reinstalling either, all existing files and software are intact.
