All the Sun color framebuffers with 13w3 ports that I've ever seen
demand composite sync.

That'd be Very Strange for a Sun framebuffer.

If you know that the display doesn't do composite sync, that's almost

the 13w3 port, that might also be your problem. I can mail you a
Sun-badged one, if you like.
