So, two D525MW Atom computers running Linux with an RTAI patched kernel,
the Asus/ Phenom computer is part of your CNC workflow, and you have
software that needs to run on all of them.
The simple answer would seem to be to run the same Linux distribution,
kernel, and RTAI patch on all three computers. What Linux distribution
and kernel do you run on the Atom computers?

You might want to try the USB system drive trick in all of the computers
(Atom, Phenom, and laptop) to see if it works. If so, you have more
options.
How long will that battery power the laptop?
If you remove the battery, will the PSU run the laptop?

I've been running SanDisk Ultra Fit flash drives as system drives for a
few months in four machines. So far, so good. It will be interesting
to see how they degrade and/or die.

Okay, "all the eggs in one basket". So, either a USB flash drive or the
newer 1 TB drive as the system drive, migrate your data to a new 2 TB
drive, migrate the Amanda archives to the other new 2 TB drive, and then
keep the older 1 TB drive as a spare or use it as an on-site copy of the
Amanda archives.
I still think it's a good idea to move your personal desktop into the
laptop. If you use an IMAP mail server and keep your mail there, you
can get to it from any machine with an IMAP mail client.
Our home was burglarized in January. Thankfully, vital documents were
in a safe deposit box at the bank. The burglars took cash, jewelry,
perfume, collectibles, cameras, a game console, a game, etc.. The
burglars didn't mess with my computers or backups, but I was glad I had
off-site backups anyway -- I have 20+ years of computer programs,
documents, and data that would be difficult, expensive, and time
consuming to replace.
