Well, here's the short answer:
The reason you have a ISA to PCI bridge still is that the serial
ports, parallel ports, floppy, keyboard and mouse devices still live
on the ISA bus. They aren't full PCI nodes just yet in most hardware
designs (I've yet to see a floppy, keyboard or mouse on the pci bus,
but I'm sure people will tell me where I can find such beasts).
