The following article (attached here as a PDF) is the body of the article that appeared in the 2/2009 issue of BSD Magazine. It describes how to install NetBSD on the Kurobox Pro, using a patch provided by Kiyohara. The article was written to use Cygwin for the build environment (see Hillary, Sir Edmund - "Why I climbed the mountain"), but should work just as well with real versions of *nix.
If I get the time, I'll make it into a real wiki article. Meanwhile, enjoy.
Note: At least for the time being, you can download the entire magazine from bsdmag.org.
