It only afects the *defaults* of various driver knobs that can be freely
modified at runtime:

without THINKPAD_ACPI_INPUT_ENABLED:
hotkey_enable = 0
hotkey_mask unchanged from whatever is already set

hot keys from ibm-acpi 0.14 are mapped to KEY_UNKNOWN, and thus will
generate ACPI events if hotkey_enabled is set to 1.

with THINKPAD_ACPI_INPUT_ENABLED:
hotkey_enable = 1
hotkey_mask = hotkey_recommended_mask

most hot keys are mapped to something other than KEY_UNKNOWN, and
thus will not generate ACPI events but rather input layer events.

You should select whichever works better with your userspace.
