add a driver for "PCI 'universal' communications" cards, that is, PCI cards
which contain 'standard' com- and lpt-type ports. Some of these present as PCI simple-communications/serial or simple-communications/parallel devices, but many do not. (Additionally, there is no document that I can find that describes the "specific well-konwn register-level" description of how the 'standard' devices' config space headers shold work.) Eventually, some of the devices driven by this code should become simple pci attachments for the 'lpt' and 'com' drivers, but that requires solid documentation.
