Easy enough to add.  Should be a separate device with its own pci id
though.  According to the linux source code there seem to be two
common ways to implement this:  A single, large pci bar where all
uarts are mapped one after the other.  Or one pci bar for each uart.
Now I need to figure which is easier to handle for windows guests ...

cheers,
