Silence hotplug printk()s in input.c
More careful probe and init in atkbd.c and psmouse.c
to avoid triggering bugs in certain keyboards.
Accept old AT (non PS/2) keyboards with limited command set.
Accept Logitech mice which can only do IMPS/2 and not PS2++.
Use a buffer in i8042.c to avoid spinlock deadlocks when
serio_write is called from within serio_interrupt.
Only ask keyboard to resent if the keyboard is there (ie no timeout).
Linus, this should fix both your keyboard and your mouse!
