No joy -- I can't suspend at all.

I build a DIAGNOSTIC kernel from yesterday's source, since I already
had a full build lying around.  Running single-user, I tried

        sysctl -w machdep.sleep_state=3

and it hung.  I realized I hadn't turned off one CPU, so I tried that,
but 'cpuctl offline 1' hung.
