Because it is time consuming, and threatens to step on things.
Enabling A20 is one thing, but this is something else... if we have the
KBC, we want to enable A20 *again* just in case. Having the i8042 code
in one place makes sense to me. This doesn't have to be done early.
The affected systems are *extremely* unlikely to ever be run without the
i8042 driver loaded, and the failure mode benign enough (if you actually
want to run a specific laptop without the keyboard driver, you can't
suspend it) that there really is no point to have yet another driver for
the same hardware that would stomp on each other.
