Sorry to reopen this old topic, but the conclusion is not obvious. The 
F13 is out and it seems to have lost support for the Geode LX CPU
(cf.http://sharkcz.livejournal.com/5708.html), due to the use of the 
NOPL instruction by GCC.

Will this CPU be supported during F13 and above or should I search for a 
new distribution ?
