There seem to be people still worried about breaking userspace with
majors/minors >= 256. I'm starting to think it is time to actually
break userspace, and dynamic majors/minors seem as good as any place to
start, especially since they by definition has to be managed by
something like udev. We have had large dev_t for something like six
years now, and most pieces of software isn't affected at all -- only the
stuff that manages /dev.
