It should works on BeOS, Zeta and Haiku. It comes as a bus manager kernel module
(acpi), which depends on one generic kernel module (dpc), plus IIRC three kernel
drivers called acpi_button, acpi_thermal and acpi_ns_dump

Unfortunatly, these no pseudo-target to build all ACPI related stuffs. Yet.

The actual targets to build are:
acpi
dpc
acpi_button
acpi_thermal
acpi_ns_dump

When built, install them here:

~/config/add-ons/kernel/bus_managers/acpi
~/config/add-ons/kernel/generic/dpc
~/config/add-ons/kernel/drivers/bin/acpi_button
~/config/add-ons/kernel/drivers/dev/power/acpi_button relatively symlinked to
previous binary.
~/config/add-ons/kernel/drivers/bin/acpi_thermal
~/config/add-ons/kernel/drivers/dev/power/acpi_thermal relatively symlinked to
previous binary.
~/config/add-ons/kernel/drivers/bin/acpi_ns_dump
~/config/add-ons/kernel/drivers/dev/power/acpi_ns_dump relatively symlinked to
previous binary.

Then, open a Terminal and type this:

$ cat /dev/power/namespace

If you're lucky, it wont crash ;-) but dump your system ACPI namespace.
In such case, stress your luck and type:

$ cat /dev/power/thermal/*



Last but not least, you may find Bryan Varner blog entries about his work on
Haiku's ACPI quite interesting or even funny:
