FreeBSD does not support suspend to disk (ACPI state S4) at all. It's
been some years since I last heard of any attempts to implement STD.
Suspend to RAM (state S3) works on some machines, including mine. If it
works on yours then I suspect use of ZFS shouldn't be an extra issue.
I haven't used ZFS, so can't comment on the rest of your message(s).
