I had the same problem and it was easily fixed by an addition to the kernel boot command.
In addition to "nouveau.modset=0" to deactivate the default driver and allow it to use the proprietary driver
I also added "vga=868" (no quotes in either one) to the kernel command.
Where 868 is the code that represents your screen found here http://en.wikipedia.org/wiki/VESA_BIOS_Extensions#Linux_video_mode_numbers

From what I can tell, once the NVidia driver starts, there is no issue, but the kernel starts before that, so the vga=### command tells the kernel what resolution to use.
