I *believe* the patch to fix that in dbus was committed last month, but
we'll still need --print-reply for a while.  I've got vague hand-wavy
plans to get rid of the deps on pm-utils entirely, or at least move them
into NetworkManager for the time being.  No idea when that would happen
though; but if somebody wanted to spearhead it that would be awesome.
First step would be convincing pm-utils to drop the NM suspend/resume
scripts, and then move them into NetworkManager git for both 0.7 and
master.  Next up, we try to figure out how much work we really do need
to do for suspend/resume; maybe we can get uevents for them instead of
relying on pm-utils or something.
