We are using a supermicro X7SPA-HF-D525 motherboard with Intel D525 as a low-power, solar-driven (fan-less) router in our African installations (e.g. www.ict4rd.ne.tz). Motherboard plus a NIC with 4*1GE optical (sfp) ports routes ~700 kpps at ~20W under full load.  There are a few papers on it if you are interested.

We are using a small linux distro optimized for routing called Bifrost.  You can find the distro at
http://ftp.sunet.se/pub/Linux/distributions/bifrost/

If you want to share your design, I could perhaps explore of we could help you implementing it under bifrost?

I was looking at a cheap replacement for a remote Jnos node and came up
with this suite:

Intel BOXD525MW Intel Atom D525@ 1.8GHz (Dual Core) BGA559 Intel NM10 Mini
ITX Motherboard/CPU Combo

iStarUSA D-213-MATX Black Metal/ Aluminum 2U Rackmount microATX Server
Chassis 1 External 5.25" Drive Bays

Added 4GB 204-Pin DDR3 SO-DIMM and a used SATA 80gb harddrive. Everything
less than $200

I could not find any intel Atom kernel configurations that addressed this
mobo but put enough together to come up with a working .config (tar.gz
attached). Probably needs more work and could use adjustment by someone
with more kernel insight than I have.

OS is Gentoo Linux with 3.2.11 kernel (kernel via genkernel with ramdisk)

The system is quite fast, passively cooled (the case fans are a little
noisy though) and like I said above fairly cheap.

If anyone jumps into the D525 Atom development, especially the kernel
config, please keep me in the loop.
