0035440536 Linux boots with no devices 
dev/tsunami.hh:
    Started commenting code
dev/tsunami_cchip.cc:
    removed unneccessary config files
dev/tsunami_io.cc:
    Added code to see the value written
dev/tsunami_uart.cc:
    conviently one of the addresses the SuperI/O southbridge can be is the same space
    as the UART. This stops the simulator from panicing although it should probably be
    changed a bit.
