Hello,
afaik, FreeBSD is unable to do a "software suspend-to-disk" (std), yes.
However, I remember it supports handing the s.t.d. over to the system
bios if your `sysctl hw.acpi.s4bios` is "1". To achieve that, you have
to have your hibernation partition configured. You can then s.t.d. using
`acpiconf -s 4`.
I haven't tried it yet because (and here comes the other advise) the
tool which creates the hibernation-partition ("HDPREPEZ") needs to
reside in the first 8 GBs of the disk. Unfortunately, this is where
FreeBSD is sitting and I was too lazy to move my F'BSD installation so
far. So, just to answer the question "where?": at the beginning. Dunno
what partition type, I recommend using your BIOS manufacturer's software
tools.
