For a really low power solution (electronic hobby, etc), sort of a micro-controller on steroids with support to Linux please checkout Bifferboard:
You can run it with OpenWrt (Linux distro used for routers), alternative OSs such as SlackWare, etc, and Special Light OS that will run from 1MB Flash.
I've done some nice things with OpenWrt, now trying to use it with the On-Board Flash Linux, making some simple C apps to communicate with external chips, getting both worlds together, Electronics and micro-controllers with Linux apps!
