Unfortunately, it seems as though much of the research community is doing Unix on micros using busses, and has forgotten much of the architecture and operating systems work from as far back as the mid-60's. As micros grow up to be as powerful as mainframes and supercomputers used to be, and as Unix has to grow up to be a real operating system, it makes sense to look at some of the problems that have long been solved and implemented.
