Backwards support for IP22 doesn't seem to be that much of a priority looking at the thread, which is a shame - I'm happy with Irix on the faster machines but OpenBSD is increasingly useful on many older architectures as an alternative to linux. It's already effectively superseded linux on sparc32 now that nearly everyone has dropped support, and I'd really like it as an option on my older MIPS stuff, like the Indy currently running Debian under my desk. OpenBSD 4.3 is looking very promising.
NetBSD has support for IP6, IP10, IP12, IP20, IP22 and IP32. OpenBSD supports more of newer machines, Linux has some IP26 and IP28 (along with IP22, IP32 and IP30?) support, and Russ Cox's Plan9 sources contain SGI Power code. Graphics aside, the opensource world supports most of the SGI machines already. The graphics being the most interesting part in most cases, the allure of IRIX will remain unparalleled, but for the server-class or headless machines, there's plenty you can still do with them -- even a 4D/20 will run the NetBSD-current
It would be nice to see this all consolidated a bit, though. Maybe someday the OpenBSD guys will import the support NetBSD has for the older machines, or the other way around.
