Comments on: OLPC now using VIA processors http://www.codemonkey.org.uk/2009/04/20/olpc-processors/ Dave Jones' Linux & opensource stuff.

See drivers/crypto/geode-aes.c and drivers/char/hw_random/geode-rng.c. There was also a way to do frequency scaling by plugging in values in an MSR, but it wasn't officially sanctioned by AMD (no stability guarantees). Quite frankly, I thought the Geode processor was Good Enough for what it was intended for. What was really lacking was RAM (256MB just wasn't enough for something like firefox w/ a bunch of tabs) and GL support (3D support just isn't there). The other missing components included a usable touchpad (which should be fixed in 1.5), a decently sized keyboard, and a larger screen. Sadly, the lack of adult-sized keyboard and screen will probably keep me from being able to retire my x40 in favor of an XO. Actually, the cs5536 does have a RNG and hardware AES support.
