I have the same issue with FreeBSD 8.1-RELEASE (i386 and x86_64) on qemu-kvm 0.12.5 (Fedora 13)
system_powerdown works properly for Linux and Windows 2008 guests, but not for FreeBSD The ACPI power button event is not received by the FreeBSD guest.
I found this (unconfirmed) status report: http://www.spinics.net/lists/kvm/msg40064.html
So it seems to be a regression...
