Unneccessary initializer.
OK, though I would prefer to differentiate "initial value is 0" from
"initial value doesn't matter".

Why do we want to have fake mode? I see it is useful for debugging,
but?
It's useful for debugging userspace too. Apps like the hdapsd daemon
can use it to figure out how often and how regularly they get fresh
readouts, and whether they often miss readouts.

URL for spec?
http://www.almaden.ibm.com/cs/people/marksmith/tpaps.html, it's at the
top of the original file.
What happens when we delete this one?
No idea, nor a way to check (on all relevant models). We've always
done it, this patch just does it a bit more explicitly and by
correctly following the H8S LPC protocol.
OK on all other comments to patches 06-08.
