yea, or you can install your own koji infrastructure and setup a
i586/i383 secondary arch, rebuild all of fedora, provide hosting,
servers,storage and infrastructure infrastructure for it.
TBH I don't know what changed between F-12 and F-13. It wasn't the
compile flag changes as I checked them so I'm wondering wondering why
its suddenly a problem. I have a mostly stable XO-1 running SOAS-2
without issues when fully updated (except for some black icons). So it
could be that for some reason we're suddenly triggering this where we
haven't in the past. Other suggestions are welcome. I'm really not up
to speed on random x86 assembler quirks between chips.
