Have you tried the geode nx? At least on earlier geodes the performance was pretty dismal. Perhaps the "nx" is a different processor than I remember. Caveat emptor. Compatible means "has the same instruction set". A 486 DX66 comes pretty close to meeting that requirement ;) > we were first also thinking about platforms which feature a intel > xscale processor, though quickly found out that it doesn't support > floating points.

This depends of course on the daughterboads you're using, and if you've got them all running.
