Hi, this diff adds a sensor for acpibtn to show lid status. This allows userland to monitor/react on lid close/open events, in case one is not using machdep.lidsuspend. I know sysutils/upower can make use of this, i just need to add the corresponding code there.
comments ? I wonder if/how the case when aml_evalinteger() fails should be handled in acpibtn_attach().. Tests of course welcome, only tested on i386/MSI Wind U100 here where LID is acpibtn0. Landry
