I was thinking more of the driver swapping around keycodes before XKB
ever gets to see them.

My laptop's keyboard has less than a hundred keys, and it's a bit weird
not to have one of them (ThinkVantage) available for binding to global
desktop actions (Lock Screen -- this was a bit funnier in older
thinkpads, where that key was labelled 'Access IBM') because all the
other keycodes under 255 are reserved for keys I don't actually have.

I realize, though, that having an extra layer of configuration in the
already messy world of input devices is not something X developers would
welcome with open arms.  ;-)
