thanks for looking into this.
It is a great idea to use nouveau with DRI_PRIME. The problem with this 
is, that it does not really work, because power management is not (yet) 
implemented. So this does not save any power, which was the whole idea 
of the Optimus technology.

But I do not understand, why you think that this bug is not release 
critical: It makes the package bumblebee completely unusable with 
nouveau, although this worked in the past.

In my opinion one of the following actions should be take:
a) Fix bumblebee/primus/mesa/... so that primus works with nouveau.
b) Include the virtualgl package again in Debian, since 
bumblebee/virtualgl/nouveau seem to work together.
c) Remove the nouveau support from the bumblebee package, because it 
just does not work.

I would prefer option a), but b) is probably easier, since that was how 
it worked in the past. If (in the long run) DRI_PRIME is improved, so 
that it supports power management, option c) could be considered as well.

Best regards,
