If you have an ACPI system, you should install acpid. Both hal and powersaved need access to the ACPI events but only one process can open /proc/acpi/event. The solution is to use acpid and let powersaved and hald listen on the acpid socket instead of /proc/acpi/event directly. Please let me know, if this solves your problem. I will then close this bug.
