Kazu was the last person to do extensive work on syscons I think. It may be less work, for sparc64 at least, to look at importing wscons from netbsd or openbsd which is much more multi platform aware than syscons. > > As a start: I think we should minimize conditional compilation based > on architecture.

Don't really know what you mean by legacy memory and I/O. Most sparc64 machines have UPA graphics, which I imagine is quite different from vga, I haven't looked into it, but there are some with just vga.
