Re: a) hooray!; b) nvidia-settings
@zBeeble: a 64-bit binary of nvidia-settings was included with the amd64 driver package; are you saying that doesn't work for you, or that you haven't been able to locate it on your system?
@rnejdl: I apologize that the crash hasn't been resolved, yet. It's the top item on my TODO list for FreeBSD, but unfortunately, it's currently behind other work. The problem is considered a blocker for future amd64 BETA releases.
