Some changes to for linux 2.6.2

dev/pcidev.cc:
    Linux 2.6 writes the latency timer, so it was added to the list of
    allowable writes
dev/tsunami_uart.cc:
dev/tsunami_uart.hh:
    A couple of changes so that the new linux autoconf serial driver thinks
    that the serial port exists and configures it
