Public bug reported:
after upgrate from Precise to Trusty nouveau driver no longer works with my
NVIDIA Geforce 8600M GT installed in Roverbook Nautilus NV-571 (aka MSI-GX600).
I see following errors in dmesg

I have limited support with fbdev driver, but only with 1024*768
resolution on 1680*1050 display, or NVIDIA 173 proprietary driver with
frequent freezes, so trusty is completely unusable for regular work now.
