i386 or amd64? It matters, which is why we ask for uname -a .. obscure
your hostname etc if needed. Some Atom models (230 and 330, I read)
have feature 'LM' and so can run amd64; others don't and must run i386.

But with hyperthreading enabled or not? How many CPUs launched (dmesg)?
Again, it matters. As I understand it, on 8.0 amd64 SMP suspend/resume
(S3) should work, i386 SMP is currently broken, i386 non-SMP should
(still) work, but I'm really not sure about the Atoms.
head -50 /var/run/dmesg.boot (or so) should clear this up. We don't
need the whole thing, but show anything to do with ACPI and CPU(s).

So, hibernate won't work. There was talk of someone doing that for a
Google SoC project but I've heard no more about it for a long while.

Slightly surprising, but again I know nothing about Atom BIOSes.

If this is either i386 uniprocessor or amd64 SMP, suspend/resume should
work, though possibly needing some settings tweaked and/or some modules
unloaded/reloaded in /etc/rc.{suspend,resume} to do so successfully.
If so, I'd next try the freebsd-mobile@ list where several people who
should be able to advise on this tend to hang out. If not, you may be
out of luck at this stage.
cheers, Ian

As Paul said, hibernation only works if the machine's BIOS supports it (hw.acpi.s4bios = 1) AND you've already prepared a suitable disk area, usually a separate slice (DOS partition) or as a file in a 'doze slice.
