- acpiconf Replace include files from old acpi driver to acpica driver. New sleep type `4b' had been added (S4BIOS) for `-s' option. Of course this has no effect because driver doesn't support it for now :-) - acpidump All needed structs in sys/dev/acpi/*.h had been merged into local header file. No changes on its usage.
