Sounds good so far.

Who does the file polling then? I saw you fdi file but don't understand
who does the work? IALd has a module system (I would call the user
space device driver) for this so that I can simply read /proc/acpi for
buttons in one driver and poll /dev/pmu for PMU interrupts in another.
HAL doesn't have such a system of "user space device drivers" yet.
