The MIT "$100 Laptop" uses the AMD Geode address@hidden  See:
  http://wiki.laptop.org/wiki/Hardware_specification

According to Jim Gettys, the reason is because it's the only low-power
processor they could find that has hardware floating point.  OLPC
needs extremely low power (~5W for the whole system including LCD).

The GX runs much slower than the NX, but consumes about 1W rather than 6-14W.
The GX is the old National Semiconductor Geode line; the NX is a low-power
Athlon core.

The OLPC demonstrator used an AMD "Rumba" development board, which you might
be able to find and try.

The simplest thing that works is almost certainly a modern laptop.
Beware of the Sony small/light ones: they use lots of custom, undocumented
chips, and won't run standard Windows or Linux distributions (they're
only warranteed when running their OWN windows distro).
