That could be a termcap issue - emacs has to see the xterm-256color entry.
But I don't use emacs, and only know secondhand about the script it uses
for setting this up.

No - the main thing here is whether your X server has enough colors available.
The 8-bit displays don't. I've tested this mostly with 16-bit displays.
xterm has defaults for the color resources (compiled in), so that's normally
not a problem. Otherwise, when color is enabled there's no additional
resources controlling whether the 256-colors are available.
