The R6 Xsun24 server supports the CG8 (RasterOps SPARC Card TC).  The R6 Xsun
also supports multiple framebuffers of the same type. (It's possible that
this code will work for a CG9, and for a CG12 as a dumb memory frame buffer.
The X Consortium doesn't have a CG9 or a CG12 at the X Consortium and so is
not able to provide support for these frame buffers.  The R6 XSun server
doesn't support the TCX framebuffer in the SPARC-station 4; use the
OpenWindows 3.4 server.)

Takahashi Naoto (Electrotechnical Laboratory, ntakahas@etl.go.jp) has
modified the X11R5 server to support the Sun CG8, CG9, and CG12 boards.  The
files are on ftp.x.org in R5contrib/Xsun24-3.[01].tar.Z.  Note that both files
are necessary to build Xsun24-3.1.

The R5 Xsun Multi-screen server is a general purpose replacement for the
pre-R6 server/ddx/sun layer; it supports multiple framebuffers of the same
type and implements several other features above the Consortium
implementation.  Available on ftp.x.org in the file
R5contrib//Xsun.multi-screen/R5.Xsun.multi-screen.tar.Z. [Kaleb Keithley, now
