This is what you should see if everything is supported from VirtualBox's 
standpoint:
# VBoxTestOGL --test 2D --test 3D --log vboxtest.log
# grep Testing vboxtest.log
00:00:00.001 Testing 3D Support:
00:00:00.040 Testing 3D Succeeded!
00:00:00.040 Testing 2D Support:
00:00:00.065 Testing 2D Succeeded!

Mine (http://people.freebsd.org/~scf/Xorg.0.log) is mostly the same except I
have this:
(II) Oct 06 10:21:03 NVIDIA: Reserving 768.00 MB of virtual memory for indirect memory
(II) Oct 06 10:21:03 NVIDIA:     access.

Also, I edited the x11/nvidia-driver port to use v256.53 of the driver. 
It is the first truly supported FreeBSD amd64 driver from nvidia.

My xorg.conf:  http://people.freebsd.org/~scf/xorg.conf
You can ignore the Non-HAL and mouse stuff.

True.  Ignore my comment on that.
