See bug 206711. 64bit CUDA maybe broken unless the error confusingly
indicates the lack of hardware support a la nvEncodeAPI. I can still
reproduce on nvidia-driver-384.47.

Before confirming make sure linuxulator passes through 64bit DRM ioctls
by testing a 64bit OpenGL app. If OpenGL still fails apply the patch.
For one, www/linux-flashplayer installs 32bit plugin thus x11/nvidia-driver
users may not have noticed.

Why? 32bit CUDA should work fine but performance may suffer.
