Oh, and is "01.org" really the right place for that?  It looks like an
Intel document, so I'd expect it to be somewhere on intel.com.

I'm still a little confused.  That doc seems to be about *software*
and Linux software in particular.  But when you said these "devices
are not designed to run in an untrusted environment", I thought you
meant there was some *hardware* design issue that caused a problem.
