	Support the tablet device in the Toshiba Portege M200 Tablet PC.
THis device is listed in uart_bus_isa.c already, however the device is not
visible on the ISA bus, and instead must be accessed via the acpi bus.
This patch has been successfully tested with the x11-devices/input-wacom
port, and works fine.
