Yes, it is. "cgthree emulated" means the driver is presenting a view
that looks like a cgthree - an 8bpp framebuffer.
Look back thorugh the list archives a bit; there's been some discussion
recently about X on the cg14. I hacked on the driver and the X server
and got it to work; I believe there's someone else working on rolling
what I did into NetBSD's current source tree. (I used Consortium X
rather than xsrc X, and a rather old kernel.)

The only thing you're doing wrong, really, is expecting it to Just
Work.
At a minimum you will need to turn on CG14_CG8 in your kernel options;
that _might_ be enough to get something working with Xsun24 -cc 4.
Better would be to go through the archives. The most recent two
messages that look to me as though you may want to read them are
http://mail-index.netbsd.org/port-sparc/2003/02/15/0008.html
http://mail-index.netbsd.org/port-sparc/2003/02/25/0002.html
but you may also want to read the rest of the messages in the threads
they belong to.
