4.x doesn't use ACPI for device resource allocation (etc), I believe, so while 
ACPI may be enabled in the BIOS, it's not being used by FreeBSD.  The limited 
ACPI support in FreeBSD 4.x is for power management.

It would be interesting to know how 4.x probes the hardware vs. how it apperas 
in the 6.x dmesg.
