Description
Installed Linux Mint 17.1, installed all package updates to current (12/Mar/2015).
Reboot, dmesg reports unknown chipset from the nouveau kernel module:

X starts up, there's no mention of nouveau in the Xorg.0.log, and it uses the intel X driver because the system has i915 and nvidia graphics. With intel-driven X11 there's a GPU hang bug, so I wanted to get the nvidia working, first via nouveau.
lspci lists the intel graphics as VGA controller and the nvidia graphics as "3D controller":

At some point in the past two days of messing with this laptop I have had the system recognise the card and "nouveau" be part of the Xorg log, but that may have been after installing the proprietary drivers or something else. At the moment I think the nouveau kernel is simply not recognising the chipset code of the card.
