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).
