Visuales are and X11 thing. Read the X docs.
The app is probably looking for DirectColor
and you have a TrueColor (the default for
high color depths) server. Some cards support
hardware overlays (3Dlabs, SGI and Sun ) but
XFree86-3.3.x doesn't. You need to change the
code to use a different visual, or start the
Xserve with a different visual class.
Read the X, Xserver and XF86Config man pages.
and lots of X programming books for info on
visual classes. I just know they are a pain.
