It's hard to judge from messages on the list whether Xfree86 or Xorg
from pkgsrc work, and if so whether it's on 4.0 or a recent -current.
Any advice would be greatly appreciated!

All right, I'm the one responsible ;)
Xorg from pkgsrc won't even build but I made NetBSD's own XFree86 work.

If you have Revision 4 hardware you can just X -configure and that's it. The chips driver is built on shark and should come with the xserver package. All you need to do is pick a video mode and colour depth ( but don't expect too much, the ct65550 has severe memory bandwidth limits, it doesn't really support more than 16bit with hw acceleration so you can choose between 800x600 in 16bit and 1024x768 in 8 bit ) If you have Revision 5 hardware ( much more likely ) you can use XFree86 with the wsfb driver. It's unaccelerated and it will use whatever video mode the console runs in ( currently 1024x768 in 8 bit ). I have code in my source tree to allow 16bit colour and more or less arbitrary resolutions and at some point I'll hopefully get around to write a basic IGS2010 driver for X. The code isn't committed yet because it needs testing on the JavaStation Krups which uses an older version of this graphics controller. I probably broke the krups support in several horrible ways. X with wsfb depends on a graphical console ( using igsfb on rev. 5, I didn't port chipsfb for the r4 yet but XFree86's chips driver knows how to switch video modes ) - the generic kernel should come with igsfb IIRC so you should have everything you need to get basic X support going.

There should be an example XF86Config for wsfb in ftp://ftp.netbsd.org/pub/NetBSD/misc/macallan/shark/
