You need to use the input subsystem utilities (specifically, input-kbd) to map the scan codes to particular keys. (There's a list of defined keys in "/usr/include/linux/input.h".) To give you an idea of how to do this, I've attached the shell script that I use for initializing my machine. It's got some unrelated stuff, but performs all the initialization of the thinkpad key mapping. I've also attached the keyboard map that I use. Together these should give you an idea what to do, provided you can read shell script. I wish this was simpler, but there are still some rough edges. At least it's possible to get useful behavior, even if it requires a bit of bit-twiddling. PS: Many thanks to Henrique for implementing the input features in thinkpad-acpi, nicely documenting it, and answering my questions as I was figuring this out.
