I've reviewed the patch [1], and I disagree with your assessment.  It
would work without any tuning to specific systems.  The learner would
learn that system response correlates to the face.

It would only work on Linux, but since that is a dependency of Sugar I
can't see how non-portability would be an issue.  The code gracefully
degrades if /proc entries are not present.

It uses documented Linux kernel interfaces, which may be invalidated in
future, but those interfaces have lasted a long time without significant
change, and there are many tools that depend on these interfaces.

I'd be more concerned about your concern if I could understand how you
drew your conclusions about the function not working without being tuned
to very specific systems.

As a general rule, I would expect no help from coders who contributed
code to an open source project in the past, but help is always welcome,
and the contributor could be one of the first people to be asked when
code breaks.
