>From the XFree86 4.0.3 man page:

       -pixmap24
               Set  the  internal  pixmap  format  for  depth  24
               pixmaps to 24 bits per pixel.  The default is usu­
               ally  32 bits per pixel.  There is normally little
               reason to use this option.  Some  client  applica­
               tions  don't  like this pixmap format, even though
               it is a perfectly legal format.  This is equvalent
               to the Pixmap XF86Config(5x) file option.

Maybe that's what you need. I don't know if XFree86 3.3.6 has that option.
