It snapshots the system and returns, producing the same console output
as s2ram (is this the expected behaviour?)  I ran this several times in
a loop, and experienced no problems at all.  Maybe it depends on the
amount of memory used...  I saw a freeze saying "99% done" (ie. not
100%), btw.  Are other pm_test values meaningful with s2disk?  Is this
handled explicitly in s2disk, or does simply the kernel act as if it was
resumed instead of providing the system image after SNAPSHOT_CREATE_IMAGE?

No change on this front, FWIW.  But rc7 is out now, I'll test again.
