Yes and No. All event can fit to input api. but some of event is well handled by 
acpi event handling scheme,I think.

For example, lcd brightness control. This feature on Panasonic laptop is implemented 
on acpi dsdt, so it is derivered by hotkey driver. I think these features controled by 
acpi subsystem should handle in acpi/acpid scheme.

In my pcc_acpi driver, acpi-handler and hotkeys utility combination, 
setting values of lcd brightness is done by acpi-handler that acpid call.
And hotkeys utility displays values with reading brightness from /proc/acpi/pcc/dc_brightness.
