Given the loud feedback, I've updated the proposal at:

The revised proposal:

- Build all packages for i686 (this requires cmov)
- Optimize for Atom

Why?

- We don't really support i586 in any meaningful matter
- OLPC still works with base i686
- We are likely doing a mass rebuild for F-12 anyways, might as well
switch
while we're doing it
- Atom is the only currently produced 32-bit x86 chip of note; optimize
for what's currently available
What about Pentium M family aka Centrino?

The Pentium M chips are powerful enough not to care too much about 1-2% optimizations IMO, Atom is another story.
