I've built UP kernel and disabled APIC in /boot/loader.conf:

hint.apic.0.disabled=1

Issuing zzz or acpiconf -s 3 causes the system to freeze. Only the lcd 
backlight is turned off - cpu fan, hard disk and led indicators are still 
working. Pressing power-off button or hitting random keys doesn't wake up the 
system. The only way is to hold power-off button for longer than 4 seconds 
and completely turn off the notebook.
