You could look at your DSDT, it is in /proc/dsdt. it is possible to disassemble it with "iasl" which should be available either in repository of the packages for your Linux version, or as part of acpica-unix, available at www.intel.com. Look for a device with id from /drivers/acpi/fun.c file (PNP*). If such a device exists, then we should deliver it to you as /proc/acpi/fun/name. > bye...masc. > - Regards, Alex.
