I should also mention, it seems we're talking about two different things.
There is limited CUDA support w/in the linux emulation layer for
nvidia/cuda,
but the native nvidia blob for FreeBSD hasn't had this support for well
over the ~20 years (or more) I've been using FreeBSD.

That's an important distinction.

Also, it's maybe true that they've added support within the past year to
the native blob, but when I was building my machine not than a year ago, it
wasn't there.
