I don't believe that the MIT X11R4 server exploits the GX board.  In any
case X11R4 contained many performance improvements over R3 and so the
Perdue enhancements became obsolete.  If you have a Sun with GX it is
probably worth your while to fork out some cash for OpenWindows.
OpenWindows will use the GX board if present.  I believe the price is
about $400 but I'm not certain of that.

Note however that the GX board only improves performance for operations
like line drawing and area fill.  There is no significant improvement for
BITBLT operations.
