Hmmm, it seems that it is also controlled by acpi, because in a kernel without your fix the Powerbutton produces also these errormessages like the volume keys and all fn+Fx (only fn+F4) always gives the right action... So as I see the things in the moment, I prevent with the fix from giving the errors, but I'm not get any more usable events in /proc/acpi/events  cause fn+F4 and the LID-switch worked also before. The only difference in usability is that I can now use fn+F7 again to switch between the displays (internal/external).

It seem that I'll need it for acpi on that Laptop....

Thanks to all who work on ACPI-support for linux
