All hotkeys go to the input layer.  There is an thinkpad-acpi input device
where the hotkey-related events show up, and that input device has a keymap
which you can reprogram to generate whatever key code you want.

Other HKEY events that are NOT hotkeys go to the ACPI *netlink* event layer.

Some distros have a daemon that listen to the new-style events, and
synthesize old-style procfs-like events for the acpi daemon.

The thinkpad may send hotkeys to the keyboard controller instead of using
the ACPI HKEY 0x10xx events block that thinkpad-acpi processes.  In that
case, you have to find the events elsewhere, and you may need to interact
with the kernel and keyboard input device to set the keycodes and scan codes
up.
