Atom has up to SSE3 :
http://en.wikipedia.org/wiki/List_of_Intel_Atom_microprocessors

The VIA CPUs slowly acquired extra instruction across the various lines and
iterations, from C3->C7->Eden->Nano. I believe the newest Nano CPUs even
have SSE4.

I am not familiar of the computational needs of an automated irrigation
system (I'll speculate relatively low), but if up front cost is important,
why not just get used system? Way-cheap P4-era systems seem to be common
around my part of the world, these days. They're going to burn more power
than a new Atom-based system, but will likely cost about a quarter of the
price, up front.
If you're looking at the long term power consumption, check out the Fit PC
http://www.fit-pc.com/web/
or Norhtec's array of offerings (Vortex86 and VIA CPUs) :
http://www.norhtec.com/products/index.html
I am particularly looking forward to getting one or two of these in from
Norhtec, when they are released :

Or, if your heart is set on a bare Atom motherboard, here's a few upcoming
options:

Experience with Linux + Atom : I built my (light duty) fileserver around a
Jetway Atom330 motherboard. I'm running Slackware 12.2 on it, has a single
2G stick (max), a 4xSATA daughterboard + 2xSATA + 1xIDE, realtek onboard
gigalan. I'm pretty happy with it, seems stable enough on XFS across all
the drives, think I've rebooted once in the past year due to a (stock)
kernel bug in the (unneeded) sound module, otherwise it's up 24/7/365. I
may pony up for one of those Zotac NM10-B-E boards at some point, perhaps
the Supermicro X7SPA-HF, mainly for the increase to 4G RAM (2 slots).

Yup, computational needs could be handled by by practically anything. The
O/S and any GUI would be the biggest loads. The system would just be taking
readings from a weather station and other sensors on a 1-wire system and
doing things like activating relays and the like based on the readings.

I've got an Athlon Barton 2600+ system that could be used but it's too noisy
to run in the house 24/7. The garage is not a PC friendly environment (too
much dust and temperature extremes.)

Cheers
Mike

Have you looked at something like a Chumby? It comes with Linux installed.

Lots of little computers out there these days...

I've also been weighing the benefits of keeping a computer in a varying
temperature (outdoor). Sounds like condensation is a killer. From what I've
read so far, one almost certainly needs a sealed system during the cold
season. Dust can be filtered, but water vapour has to be accommodated for.
