Hello, I was asked about the x.org drivers NetBSD is maintaining a while ago. Here is the list. I think we're quite happy to continue maintaining these, but an external developer was interested in upstreaming them.
All of the code is under the X11 license and unlikely to compile on non-NetBSD without a little patching, at the very least due to using wscons-specific ioctls. This is the most important one: xf86-input-ws Input driver for mice, touchscreens, and touchpads shared with OpnBSD https://github.com/NetBSD/xsrc/tree/trunk/external/mit/xf86-input-ws Most of this hardware is quite old and hard to find: xf86-video-ag10e "accelerated driver for Fujitsu AG-10e graphics boards" (SBus-based device) https://github.com/NetBSD/xsrc/tree/trunk/external/mit/xf86-video-ag10e/dist xf86-video-crime "accelerated driver for the CRIME rendering engine found in SGI O2 workstations" https://github.com/NetBSD/xsrc/tree/trunk/external/mit/xf86-video-crime/dist xf86-video-igs "a driver for IGS CyberPro 2010 graphics controllers" (apparently used on StrongARM-based Digital DNARD machines) https://github.com/NetBSD/xsrc/tree/trunk/external/mit/xf86-video-igs/dist xf86-video-mgx Southland Media MGX framebuffer driver (Sun hardware) https://github.com/NetBSD/xsrc/tree/trunk/external/mit/xf86-video-mgx/dist xf86-video-ngle "a driver for HP's NGLE family of graphics chips" (used on PA-RISC hardware) https://github.com/NetBSD/xsrc/tree/trunk/external/mit/xf86-video-ngle/dist xf86-video-pnozz SBus Weitek P9100 driver "this driver has been tested on SPARCbook 3GX and 3TX, it supports full acceleration in 8, 16 and 24 bit colour" https://github.com/NetBSD/xsrc/tree/trunk/external/mit/xf86-video-pnozz/dist
