If you have a Creator 3d you should be able to run either 8 bit or 24 bit,
regardless of what the X desktop is set to.  In fact, any display adapter
which supports 8 and 24 bit simultaneously (as shown via
/usr/openwin/bin/xdpyinfo) will support either 8 or 24 bit mode.

There are *SOME* display adapters which support ONLY 8 or 24 bit mode, and
not both.  SunPCi should do the right thing, i.e. if you configure SunPCi
for 8 bit, reconfigure your desktop for 24 bit, then restart SunPCi, it
will detect that 8 bit mode is no longer available and start up in 24 bit
mode...  It will also show that only 24 bit mode is available if you look
in the Display control panel app.
