I highly suggest you leave them alone.  These are _NOT_ general use keys in
the T42.  Or on any IBM ThinkPad, for that matter.

Reprogram the keymap if you want to mess with it, but you cannot override
its function to toggle the thinklight unless you hack the DSDT.  That's why
it doesn't generate any keycodes by default.

Read the thinkpad-acpi driver documentation...

What functionality are you looking for?  Broken volume response?  Reduced
lifetime on your LCD inverter and bad backlight control behaviour?
