In order to display 8bit (256 color) applications that use pseudocolor visuals (paletted or "indexed" color), you need to use a 8 bit depth. If you are in 16 or 24 bit depth, your application does not have a palette to use, and can not function. Overlays, are a feature of modern hardware that allows you to use 8 bit pseudocolor applications while you are in a truecolor visual, etc. In order for this to work, your hardware must first support overlay, and in the depth and res you are using, and your video driver has to implement support for the overlay. Your X config file must then be configured to enable overlay support as well. In the case of Matrox hardware, you can find the documentation on the "mga" manpage. Hope this helps.
