I supplied the original pile of Blade 1000 and 2000 machines to Theo and the
2006 OpenBSD hackthon.
You should take an OpenBSD sparc64 snapshot and try it. It is extremely
usable and stable. Mark Kettenis has made huge leaps in working around the
myriad of bugs in the processor and associated glue logic. Ultrasparc III
running OpenBSD is solid and keeps getting faster.
Originally, the initial patches and commits had extensively IFDEF work to
ensure that earlier versions of Ultrasparc wouldn't break. The code has been
fully integrated into the tree for a number of months.
Also, a few days ago Mark committed a driver for the Cassini network
