The "sources" you see there are the following:

- A Makefile
- The Nvidia binary module
- Some source code that wraps around the binary module and interfaces to 
the kernel functions, agp, etc.

This gives some flexibility when it comes to using it with different 
kernels, The "kernel layer" compiles against and uses information from the 
kernel at /usr/src/linux (or the one you specify through parameters). This 
also means they don't have to release a new binary for every kernel release 
(can you imagine how horrible that would be?), or track a huge number of 
kernel changes.

Most of the guts are still a closed binary module (for x86 only) that 
hasn't had any peer review.
