cg6 on sun3x (3/80)

Has anyone done any work on supporting a cg6 on a sun3x?  The cg4 in my
3/80 died, so I took a P4 cg6 from my 4/330 so that I could test out Xfree 4.
Then, I noticed that there is no code to support the cg6 (and cg8, cg9) on
sun3!

It seems that the way to do this would be to include files.sun and set it
up like a P4 cg6 on sparc.  However, including files.sun causes duplicates
for bwtwo, kbd and ms.  Should the sun3 code use the code from dev/sun or
should a cg6 driver be separate, like the rest of the sun3 drivers?

Thanks,

J
