Rewritten the PS/2 poll (without the password security state, that is yet to be done) and enabled the PS/2 KBC IRQ latch on all PCI machines as well (it is present at the very least on Intel SIO and PIIX), fixes Windows for Workgroups 3.11 input, and reduced mouse polling to 255 Hz (the maximums supported by PS/2 mice).
