I couldn't get the git kernel, so I tried that patch against linux-3.7-rc3.
Unfortunately, it didn't change anything in my set up (Elitebook 8530w, NVIDIA
Corporation G96M [Quadro FX 770M] card).

It appears that even the blob was experiencing the same issue [1]
Affected blob 180.44, fixed in 180.60. I would expect that a specific quirk was
added to handle the issue

There should be a solution to this dilemma, considering that nvidia's binary
blob does it correctly.
