Pardon? NetBSD has UltraSPARC support for ages. Though, US III support
is relatively new. Best would be to run a NetBSD-current snapshot on a
V240. At least that's what I run on my V240...

p.s.: I have to admit, there is or was a nasty SMP bug that made US IIIi
machines crash under load. This affected only US IIIi, not US III
machines. Work around is / was to disable all but cpu0 upon bootup via
cpuctl(8). I don't know if this was fixed in the meantime. At the
moment I prefere to play with my VAXen and PDP-11s... So I am not up to
date regarding NetBSD/sparc64.
