Definately new info to me, thanks.

Unfortunately, even though xdpyinfo reports the extension is added if I
specify a depth of 8, it still won't start if I specify a larger color
depth.

Also interesting, if I do just start up a session with a depth of 8, and
try to exec a gnome-session from an aixterm window - it crashes.   Of
course, the only thing in my .xerrors file is "connection to server
lost..."

Now looking more carefully at the xdpyinfo output, below the place where
it says there are three color depths available, it also says:

depth of root window:    8 planes
  number of colormaps:    minimum 3, maximum 4
  default colormap:    0x37
  default number of colormap cells:    256

yet my programs that complained about lack of color still work, even with
netscape running....I have got to be going down a garden path here
