Bug#988200: xserver-xorg-video-nvidia: user-specified xorg configuration can't find nvidia driver

[Ian Eure]

Adding, this issue means Xorg can’t detect the nVidia GPU *at 
all*, even if you simply fire it up with no special configuration. 
Perhaps it works on machines with a single nVidia card?  But on my 
machine with Intel and nVidia, straight out of the box, it doesn’t 
work *at all*.

Verified that the same situation exists in 470.141.03-1, which is 
the current version in sid.
