The R8000 code was removed because it was unfinished work in progress. I
wrote it without having access to hardware at the time. If somebody was
submitted the code for inclusion in that shape I'd have to reject and
consequently I removed the R8000 code again.
I think we have sufficient knowledge about the R8000 to get it to work.
And if necessary I know the folks who did the IRIX kernel work back in
the dark ages.
