Sure, I'll get there eventually ;)
There are some new drivers too ( for old hardware though ) which for now are kinda NetBSD-specific ( I made no real attempt to keep them OS-independent since I didn't think anyone else would want them - the NetBSD-specific part is only about /dev/whatever and mmap offsets so that would be trivial to port should anyone want to do that )
- xf86-video-crime, for the SGI O2. Register and DMA buffer mapping is NetBSD-specific and stuff like mode switching is done by the kernel driver, should be easy enough to port. The biggest 'challenge' ( if you can call it that ) on Linux would be the fact that this driver expects the framebuffer in tiled mode while Linux' kernel driver uses a trick to make it appear linear ( which the drawing engine can't deal with ). Since we use the drawing engine in the kernel as well it's always tiled and I threw out the linear hack long ago.
- xf86-video-ag10e, for the Fujitsu AG-10e SBus monster. More or less a glint, an i128 and a Weitek P9100 behind an SBus-PCI bridge, glued together with an IBM 561 RAMDAC. This driver talks to the glint. Kinda obscure and hard to get but one of the few accelerated 24bit SBus cards that won't melt the case.
- xf86-video-igs, for IGS CyberPro 20x0, written for NetBSD/shark so it only supports the VL variant. Adding support for the PCI variant should be trivial. There's a bunch of sharks floating around ( they're small StrongARM-based network computers, technically all prototypes but DIGITAL made tons of them ), Linux has been ported long ago - no idea if anyone's still running linux on them. I use mine as Xserver debugging aid ( read: second head with keyboard and such that just needs to be plugged in, is silent and can run a bunch of xterms and editors )
Question is, would it make sense to have any of these on freedesktop.org? The crime driver would probably draw a little bit of interest, not so sure about the others.

have fun
