That's farther than it gets on my system. It looks right up until the
fatal error.

This one is beyond me.

It's supposed to work. It's just not finished, and whoever was working on
it apparently is doing other things right now.
As best as I can tell, XF86's Xsun/Xsun24 servers don't officially even
know about a cg14, and I suppose that's why they try to drive it as a
cg8.

Someplace there has to be documentation on how to interface with these
devices at the driver level: After all, Jelinek, Rehacek, and Miller got
the information from which they did the xfree86/sunxxx drivers somewhere.
If I had that and some clue how Solaris interfaces with these devices, I'd
try to ferret out what's going on, but I don't. If Sun makes any of this
information available, they call it something else.
Sorry I can't be of more help; I find it frustrating that XFree86 doesn't
provide a road map, at least, for completing xf86/sun support in general,
and Solaris specifically. (The in general part, because although the
drivers do work with Sparc/Linux, they are not yet functionally complete.)
Let me know if you come up with anything,
Ferris
