Just a note, I believe that the ia32 support should
"concentrate" on
netbooks (So Intel Atom), those are the only new things on the market
that can't run x86_64, and the userbase of those will just grow and
every percent of extra performance will make many people happy.
So we should ignore OLPC that is deploying 100's of thousands all
running Fedora?
A benchmark run on one of those might be very useful to make the
final
decision, not that the more server-oriented tests are very useful for the
typical netbook userbase.
Benchmark for an OLPC device would be good too.
And then there's the "should work even with this"
decision, and i686 without
cmov is a reasonable minimum there. Could be i686+cmov or +sse2, but those
will make a lot of people unhappy.
Pretty sure OLPC supports cmov thought but definitely not SSE2.
