Thanks a lot, this really helps. I'm now beginning to
build my dreamcast and sparc machines to test it out.
This is going above and beyond my expectations for a
response!

Copying netbsd-docs in case this is something that
someone might want to put on the site. I don't think
there is anything there like this. This is nice for
maintaining a large number of machines from one source
tree.
