Hi Pierre,
I have tried the diff patch (3 changed lines) on  Kernel 3.13.5-gentoo, and did
a quick test on nVidia 9600m GT: The screen gets scrambled as soon as nouveau
is loaded. At the startup, EFIFB is used and works with full screen resolution,
but the colors are "incorrect". EFI is setup to use 9600m as default.

I am still using nouveau without acceleration. I will be testing the patched
Kernel on nVidia 9400m, by modifying EFI to use 9400m as default.

Could you do a diff on your patched kernel and unpatched, so that we could find
other differences?

Thanks.

BR
