The athlon NX isn't too bad (Athlon XP essentially), and there is an
embedded opteron line too.

Freescale makes lots of powerpcs that use much less power than the atom.

I suspect that's a long long time ago. Sparc used to have use in
printers and other things as an embedded controller. I haven't seen
that for years though. The last time I saw/used one was inside a kodak
dyesub printer which would be well over 10 years old these days.

Certainly some use in embedded designs. Pretty decent linux support too.
The SuperH used to have some use in game consoles, but that's a while
ago now.

Most wireless routers are MIPS these days, as are china's own cpu
(loongson) these days (which make anything intel makes look like a joke
when it comes to performance per watt).

Some of those are pretty old and small, although still in use in some
cases.
