This looks suspicious:
[ 4.607278] fb: conflicting fb hw usage nouveaufb vs EFI VGA - removing generic driver [ 4.607298] Console: switching to colour dummy device 80x25 It
The dummy device is not connected to anything, it should say say 'frame buffer device' or something. Can you post a dmesg of the working kernel?
Judging from xrandr it can detect all outputs fine, so it seems to be a bug in handoff.
Also can you try to boot linux with 'noefi' on v3.4 to see if that works around the bug? I would like dmesg from that as well. :)
