F12 to require "i686", but which CPUs do not qualify?

[Tony Nelson]

I'm late replying -- had trouble with my mail server -- so I'm moving 
all my replies to Bill Nottingham's post, as I think he can fix the 
wiki pages most authoritatively to not say that Athlons will not work,
if that is indeed the proper thing to do, given that so many packages 
depend on packages that are only built for SSE2.

<https://fedoraproject.org/wiki/Talk:Features/F12X86Support>

If necessary, I can install Rawhide and see if it boots, and then edit 
the above wiki page and the Alpha release notes, but I'd prefer if 
someone who already uses an Athlon-core processor on Rawhide did it.

According to that link, an Athlon is specifically excluded.  According 
to the Talk:Features/F12X86Support link 
<https://fedoraproject.org/wiki/Talk:Features/F12X86Support>, SSE2 is 
required.

If that has changed, then those wiki pages need updating, as well as 
the Release Notes and release announcements.  Thanks.

That doesn't actually quite say about SSE2, but at

Bill?
