Does it generate interrupts under FreeBSD? I'm not sure if their
ACPI module is compiled with debug supports, though.

similar to that of early FreeBSD 5, with some modifications to
compile with newer ACPICA code and some fixes ported over from FreeBSD.
I think there are still a lot of things to port from FreeBSD.
