Just to posit, if you are intending on installing the nvidia binary driver
on a niche built by hand system, then I don't think the glibc overheads
would give you much cause. Wierdly you'd have gotten better battery
life most likely using the binary driver since -nv doesn't have any powersaving
abilities. So you are probably shooting yourself in the face to spite your foot
or something.
