Some minor fixes, the PS/2 mouse command F0h (set remote mode) is now implemented, the PS/2 mouse command F3h (set sample rate) now actually changes the host mouse polling rate, and the Intel SIO IB and ZB now forcibly initialize a keyboard and mouse IRQ latch if the board has a PS/2 keyboard controller, to simulate the presence of a latch external to the chip.
