NetBSD probably won't boot on those machines, but it would be
interesting to put in some effort to get it to do so.   Basically
anything with an R4400 in it isn't going to work without some hacking.
There's a guy off in Europe somewhere (I could track down his mail)
who's been working on a R4000 port that he apparently has working.
Maybe you could work together to get something to boot.
