Thanks. See below.

Oh, okay, now I understand. It is wonderful that it works, but
reasonably unexpected. We don't build from the Linus tags often, we use
a separate branch. That explains why I've never seen that kernel
version on our builds.

I said some very early versions cannot be safely upgraded, I didn't say
it would harm OLPC.

I have just now tested with an XO-1, downgrading from Q2E45s (SVN HEAD),
to Q2E25 (your version), then allowing the OLPC OS 11.2.0 development
build os20 olpc.fth reflash to Q2E45 (stable), and there were no issues.
Your serial number CSN748012AB should not be harmed by reflash to Q2E45,
and this reflash would happen automatically if you installed the latest
stable OLPC OS 10.1.3. We would have heard about it by now if there was
a problem with Q2E45 that harmed XO-1.
If necessary, you may reflash back to Q2E25, but I cannot recommend this
because of the significant problems that were fixed after Q2E25.
You might ask your users what firmware version they are using.
