I think the extra colors on console won't hurt, now that I know about the 2048/4096 setting. > Is there a special reason not to use the X* trident driver? Yes, I had crashes when using more than one X display (e.g. one local xdm and one "X -query other :1"), and switching between X and console is _much_ faster this way.
