Rink Springer has also expressed interest in this. Perhaps Kip can explain some more about what things he looked at, but the most serious bugs might be in pmap or perhaps trap handling. Operationally, things like buildworld -jN die quickly with random signals, kernel traps, etc. Kris P.S. It looks like marius has made progress on US III but sun4u is still an architectural dead end.
