There are plenty of machines with 32-bit only CPUs (such as early Celeron,
Pentium socket 478, even some Core Duos [Apple Mini]) which run Fedora very well.
Many are less than 5 years old. In the US, that means the depreciation rules
of tax law strongly encourage their continued use.
IIRC, when we stopped supporting i586, someone kindly ran some tests of
the various -mtune options, and atom optimization turned out to work
best for almost all the processors tested - it's not _just_ good for
Atoms. I could probably drag that post out of the archives if I weren't
a lazy good-for-nothing, but I am, so, what you get is my
probably-faulty memory. =)
