For what it's worth, I was also under the impression that we were
going to recommend that people running a "genuine 80386" chip should
probably stick with the 4.x-series of releases. Even if 5.3 works on
80386 right now, I was not sure that it would continue to work for
the life of the 5.x series.
I don't know where I picked up that idea, but even if we are supporting
80386 for 5.x then I think we should be able to drop it for 6.x.
