I'm guessing by suspend/resume you mean xl save and xl restore. They
work for FreeBSD domU (with Linux dom0), tested on 13-CURRENT r342020.
I have not tested for FreeBSD as dom0 because I do not have it set up.

Roger committed it to CURRENT on July 19 [0], and AFAIK it has made it
into 12-RELEASE.

I'm guessing you replied to the wrong thread, and you meant to reply
to the ARM/ARM64 thread?
