On most graphics cards you will have to choose to either have everything

NVIDIA Quadro cards with Xorg allow turning on color index transparent
overlay (off by default).  This advertises a 255 PseudoColor X visual in
addition to 24 bit.  However, when someone says "old old software"
it typically wants the 8 bit visual to be the default, which causes
lots of problems with recent desktop managers.  Also, composite and
XRandR are usually incompatible with transparent overlay. If you are
lucky and the old old software searches for an 8 bit visual and can live
with only 255 colors (and no composite or XRandR), transparent overlay
may work.
