May be you can hack in an extra 8250 and using extra address bits for decoding the _CS line? Even a damaged 8250 is fine as long as you got enough bits for the Ethernet port.
Just need to recompile the network driver to use new address.
There is also the path of printing to a network printer. Most of the open router firmware has support for that (assuming that router and print has USB).
