I really don't like that idea that only fuels more Fedora detractors
and also feel like a wrong path. AMD Geode is the worst choice by
faras pointed out by some posters due to XO 1.0 ( I have one). Are we
going to abandon million of Fedora users that use those chipsets?
Think about people who live in developing countries no having x86_64.

Until those chipsets are fully supported as secondary arch and fully
operator without major hiccup, I will say no.
