Actually, I just missed it ... first off, from the same Section S ...
http://download.nvidia.com/XFree86/Linux-x86_64/1.0-8762/README/appendix-s.html  

  "The NVIDIA driver does not yet support the
   GLX_EXT_texture_from_pixmap extension. This extension is used by
   OpenGL-based composite managers, such as Novell's Compiz, to use X
   pixmaps as OpenGL textures. Support for the
   GLX_EXT_texture_from_pixmap extension will be provided in a future
   NVIDIA driver release."

And then looking back at Appendix D, the X config options ...
http://download.nvidia.com/XFree86/Linux-x86_64/1.0-8762/README/appendix-d.html  

   "Option "Overlay" "boolean"
        Enables RGB workstation overlay visuals. This is only supported
        on Quadro4 and Quadro FX chips (Quadro4 NVS excluded) in depth
        24 ... RGB workstation overlays are not supported when the
        Composite extension is enabled. Default: off.
        UBB must be enabled when overlays are enabled (this is the
        default behavior)."

It looks like the Overlay option in nVidia's cards is different than
ATI's.

But looking at the display settings for my running Xorg 11R6.8.2:  

  $ xdpyinfo
  number of extensions:    33
    BIG-REQUESTS
    DAMAGE
    DOUBLE-BUFFER
    DPMS
    Extended-Visual-Information
    GLX
    LBX
    MIT-SCREEN-SAVER
    MIT-SHM
    MIT-SUNDRY-NONSTANDARD
    NV-CONTROL
    NV-GLX
    RANDR
    RECORD
    RENDER
    SECURITY
    SHAPE
    SYNC
    TOG-CUP
    X-Resource
    XC-APPGROUP
    XC-MISC
    XFIXES
    XFree86-Bigfont
    XFree86-DGA
    XFree86-Misc
    XFree86-VidModeExtension
    XINERAMA
    XInputExtension
    XKEYBOARD
    XTEST
    XVideo
    XVideo-MotionCompensation

No "Composite" is loaded all while Xv[MC] is.  So I'm still at a loss
why I'm having issues, unless I'm missing some nVidia setting.
