I am a dork. Now that I've read your post again, you want to ENABLE acpi at boot, I thought you wanted the opposite.
Edit /boot/loader.conf and enter acpi_load="YES"
The initial boot menu is determined at boot time. If ACPI is unrecognisable (such as my old compaq desktop), the system will put "ACPI disabled" as first option and vice versa.
