So you're running with some kind of framebuffer support, nothing specific 
to the card. That's typically the fallback.

I've killed the splash screen at bootup and, weirdly, the boot drops into 
fb about halfway through. But it *seems* to then recover and go to the 
Nvidia driver. Which may or may not have anything at all to do with what 
you're experiencing. If memory serves, a good way to check this us to 
determine whether your Mesa support is software-only or hardware. If the 
former, you may not be using the Nvidia driver at all. Open a terminal and 
enter "glxinfo" and then scroll back to the top and see if it sheds any 
light. It should begin something like this:

name of display: :0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4

I do not believe that a framebuffer device supports direct rendering.
