sorry, that was a bad comment. I'd been using "resume" to mean
suspend-cancel and "reconnect" to mean run in a new domain. This patch
is the backwards compatible version (it sets EAX to 1 in xc_linux_save
rather than xc_linux_restore).

ok, I'll prepare that in a bit.

I poked around the elfnote route for advertising kernel features to
xend, and I have a feeling someone else should be designing the API
for that - I only want very little out of it and would probably be
shortsighted. For instance, it wasn't clear to me whether it'd be
better to have an xc function that returns almost raw elfnotes (an
array of (type, length, contents)) or only parsed, named elfnotes, or
only features.
