Would be great, but had you ever have a look at the X11 sources
themselves ? They reorganised pretty everything from R5 to R6, I doubt
that it would be easy to adapt the device dependent part of the R5
server to R6.
There is a patch to the official X11R5 server (originally intended for
Utah BSD I think) which provides hardware support for all(?) Catseye
types, the gatorbox, renaissance, ..., everything you know NetBSD
supports :-)

No and some yes, the older - Catseye for instance - type framebuffers
are pretty well known - the problem are the more recent devices like the
VRX line...

Maybe it would make more sense to adapt Linux' framebuffer device
interface to NetBSD and we would get a rather slow R6 server with rather
less work. But maybe they have kind of hardware acceleration now...
