I've ran into this too, and got this solved by blacklisting the nouveau

still on grub-legacy, don't know how it is done on grub-2 unfortunately)
This made the system boot fine, but X didn't start before reinstalling
the nvidia drivers. Doing so and rebooted I was in a functional X, just
like before the upgrade of the kernel.
I wanted to get back to you and thank you again, Andreas. A little
research revealed that KMS could be turned off on this system using a
"modeset=0" line in /etc/modprobe.d/nouveau-kms.conf. However, that
turned out to be unnecessary. I decided to do only one thing at a time
and test. Adding the "blacklist nouveau" line to
/etc/modprobe.d/blacklist.conf was all that was needed to give me my
docked external display back when booting with the new kernel. The
nouveau frame buffer is *not* used, apparently, if nouveau is blacklisted.
My system is working well now with its odd (at least in my eyes) vesa/nv
driver combination.
I filed a bug with freedesktop.org and will see what comes of it. I do
hope to be able to use the nouveau driver with this system eventually.
