Correct.  nv is the open driver, nvidia is the closed one.

This makes no sense.  You can't load both the nv and nvidia drivers for the 
same card at once.

exa support in the nvidia driver is totally up to nVidia; but since their 
internal acceleration architecture is both comparable to and similar 
performance to exa, I don't see why they'd bother.

Problems with Render acceleration in the nvidia driver should obviously be 
addressed to nVidia.
