      I have some new Sun 3/80's with Lego (cgsix) frame buffers in
them that I want to run vanilla X windows on. When I compile
and run the Sun server, it core dumps (bus error) when trying
to set the enable bits on the hardware (file $TOP/server/ddx/sun/sunCG4C.c,
function sunCG4CSwitch).
      The same code compiled on a 4/280 runs perfectly on a
SparcStation 1 with a cgsix, so I know it _can_ work. The file
<sundev/cg6reg.h> (on the 3/80, it's different on the SS1) says that
the base address of the board is different on Sun3's from Sun4's.
I assume this is the problem.
      The question is: does anyone have a patch or other fix
to the X source to make this work? Thanks in advance.
