Interesting.
I checked this myself because I thought I _was_ using ACPI.
I found this:
# grep -i acpi /var/run/dmesg.boot
KLD file acpi.ko - could not finalize loading
# devinfo | grep -A2 legacy
legacy0
pcib0
pci0
Is ACPI meant to be compiled into the kernel or loaded as a module ?
What could cause acpi.ko to not load as a module ?

That just means the drivers are present, it doesn't mean they are used. It
looks like you have 'device acpi' in your kernel config. The way to tell
that ACPI is enabled is to look for an acpi0 in your dmesg. Alternatively,
you can run devinfo to list your device tree. If pcib0 is a child of acpi0,
then you are using ACPI. If it is a child of legacy0, then you aren't.
