Not exactly the same, but similar, I'm running an Opteron 4228 HE on:
FreeBSD 9.1-PRERELEASE #4 r241041M: Mon Oct 15 23:30:25 PDT 2012
    jmg@gold.funkthat.com:/usr/src.9stable/sys/amd64/compile/gold amd64

The only "issue" I had was lots of error messages when ever powerd would ch=
ange processor speed... There is a patch out there to fix it...

I haven't been having issues w/ ZFS...  I have a fully GELI+ZFS system, bot=
h root and data store and its working fine...  I'm using an HPT2720SGL adap=
ter for most of the disks issues so far..

The system is lightly loaded, but has been working well...
