How about the XScale version of the ARM architecture? Is anybody
working on that? We need it for the Encore Mobilis port, on Montavista

It would be hilarious to me if the XO-2 had an XScale processor, and
Microsoft suddenly had to port Windows XP to it in order to stay in th
game. :-Þ

None of the Geode-specific power management code would work, of
course, but that's kernel-level stuff. It doesn't go into the .xo
bundles or the distro-specific packages.

That means, for us, Flash and drivers. There are Open Source BIOS
equivalents for some of these architectures.
