Modern input drivers in the mainline kernel have a scancode-to-keycode
translation table (or equivalent) which can be overwritten by userspace.
The mechanism to do that is the EVIOCSKEYCODE ioctl.

(This is no recommendation for lirc.  I have no idea whether a
pulse/space -> scancode -> keycode translation would be practical there.)
