I didn't know about that "obfuscation" part of nvidia "nv" driver. But 
AKAIK, the "nv" driver is under MIT license.

Didn't know that either. 

It seems we have not many real choices, then :-(

Looking at Wikipedia:

Graphics hardware and FOSS

Strictly speaking, only Intel has some chipsets which use open source 
drivers, but the handicap of these are:

1/ Very poor 3D capabilities and overall performance.

2/ If the Intel driver -for whatever reason- does not work, we are stuck 
with a blank/black screen as we (we = linux users) have no other driver 
available for these chipsets.

And what frightens me is the fact that, being Intel drivers fully open, 
there are still such problems with theirs embedded vga chipsets.

But well, let's hope Intel is doing well its homework.
