Yesterday I got a Sun Fire V240. It seems to be quite similar to the
Blade 2000. (US III and schizo(4).) I just tried to boot -current, see
dmesg below. So the obvious questions are:

What is the state of US III support?
Waht needs to be done with schizo(4) to get it going?

(I collected some experience in bus_space(9) and bus_dma(9) hacking on
ofppc and hp700. But pmap(9) fiddling is a book with seven seals to me.)
