Ouch thanks for point it out. Seems like I was day dreaming there.

Afaics there are only differences between the two
 - In the "good" case, nouveau manages to load the adt7473 i2c sensor. Not
related to your problem, but might indicate why you do not see the temperature
reading in "sensors"
 - The runtime pm tries to suspend one of the cards (assuming the latter) where
it should not have. Most likely the real problem, disable using
"nouveau.runpm=0" in your kernel command line (i.e grub)
