And it's working, but I happened to note:
Nov 18 09:59:20 localhost kernel: REDZONE: Buffer overflow detected. 16 bytes
corrupted after 0xd2375200 (256 bytes allocated).
Nov 18 09:59:20 localhost kernel: Allocation backtrace:

which looks a fair bit as if nvidia.ko is doing something ... inadvisable.
I realize that our (FreeBSD.org) "leverage" is .... minimal. But I'm pretty
sure that failing to report the issue won't help, either.
