Correct.  It's unused by ppc (and mips, which just copies the x86 one).  I
haven't yet decided if I should keep an empty file (copyright-only like
other files) or remove it altogether.

Correct.  Although I don't see a reason they shouldn't be, so my next patch
(which will also attempt ppc64) may enable them.

I just ran a simple 'dtrace -n <probe>'.  Nothing fancy, didn't try the
dtracetoolkit.  I'll try that tonight or tomorrow.
