Adding support for just those machines shouldn't be
a problem as long as it doesn't bloat the normal code
base. Linux has (well, had) support for SGI VisWS that
didn't have any influence on the standard code base.
[Had because nobody has bothered to maintain the code
past the previous SMP changes]

The DUAL ones definately seem to be IMPS. Unless

Not that I know, no. But if BSDi can publish the code
they're using for those machines, I guess the lack of
documentation problem is solved ;)
