I'm using:

trouble% pkg_info|grep nvidia
nvidia-driver-1.0.9631_5 NVidia graphics card binary drivers for 
hardware OpenGL ren

w/o obvious issues on:

nvidia0 at pci1:0:0:       class=0x030000 card=0x019010de chip=0x018a10de 
rev=0xa2 hdr=0x00
     vendor     = 'Nvidia Corp'
     device     = 'Quadro NVS with AGP 8X [NV18GL.2]'
     class      = display
     subclass   = VGA

HEAD is:

trouble% uname -a
FreeBSD trouble.errno.com 7.0-CURRENT FreeBSD 7.0-CURRENT #2: Sat Jun  2 
21:33:05 PDT 2007 
sam at stubby.errno.com:/usr/src/sys/i386/compile/STUBBY  i386

I do not "switch from X to console".
