Seeing noone else has had a go:

It seems pretty strange that acpiconf -s 4 powers it off properly.  
your hwacpi.txt only shows ..

hw.acpi.supported_sleep_state: S1 S3 S4 S5
hw.acpi.power_button_state: S5
hw.acpi.sleep_button_state: S1
hw.acpi.lid_switch_state: NONE
hw.acpi.standby_state: S1
hw.acpi.suspend_state: S3
hw.acpi.sleep_delay: 1
hw.acpi.s4bios: 0
hw.acpi.verbose: 1
hw.acpi.disable_on_reboot: 0
hw.acpi.handle_reboot: 0
hw.acpi.reset_video: 0
hw.acpi.cpu.cx_lowest: C1

.. but s4bios is 0 (no BIOS support for S4) and I wonder what's happened 
to your hw.acpi.thermal settings also, but .. just a long shot ..

What happens if you set sysctl hw.acpi.power_button_state=S4 and then 
try halt -p ? .. probably better off using 'shutdown -p now' actually.
