The doc text is wrong at this point, input processing isn't going to
vary based on this, so we shouldn't say it does. The only thing this
_does_ get used for is DRI1 SwapBuffers (on everything but savage), and
if you disable it you're not going to get DRI1 at all, so we really
shouldn't even mention it.
Still, leave the option wired up to the parser so we don't break any
DRI1-driver-using setup relying on it being disabled, and so we don't
complain about unused options elsewhere.
