1) I have been using the one in your package. Previously I had no problems with using your dsdt with Mavericks I have tried booting with the nodsdt config.. same problem.
2) my hd is guid. BTW I had tried a clean new install this afternoon, and I have the same situation.
3) I have tried safe boot and various combinations.. same problem. with verbose boot it fades to black very early so I cannot see.
4) Yes. I agree that it is hard to understand why one boots and the other does not, but that is what is happening.
