My comment here may seem to be completely off topic. However:
it is not nvidia driver that you, folks, build/compile. Nvidia driver
comes from nvidia as precompiled binary, and neither of nvidia drivers was
ever disclosed to anybody outside their company. Even the specifications
of their hardware are not fully disclosed, therefore programmers who wrote
open source drivers for nvidia hardware could not write better driver that
they wrote. Not their fault: they just don't have all necessary
information.
Repeating wrong words "compiling nvidia drivers" creates misperception,
which is wide spread for long time. It is not the driver you are
compiling, but merely interface between binary nvidia driver and
particular kernel.
I probably should add rant tags as I am ranting about the fact that some
company seems friendlier to open source than it actually is...
