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 ;)

The USRP on my bench draws about 11W. This depends of course on the
daughterboads you're using, and if you've got them all running.
