Modern CUDA toolkit is 64bit but runtime only works on 32bit (bug 206711).
Building as -m32 is probably still possible but may not fit all workloads
nor run as fast.

Just like Vulkan, just like KMS, just like encoding/capture acceleration.
NVIDIA always conveniently forgets about FreeBSD. However, the ailment
isn't really specific to NVIDIA but affects most binary blob vendors.
For one, Widevine CDM is maintained by Google but EME itself was pushed
to W3C by Netflix, a FreeBSD vendor which conveniently forgot a browser
can run on FreeBSD.
