Well, it borrows a *lot* from the PCI bus in its design.

This isn't necessarily true. It's quite common to have multiple PCI busses connected to the *HOST* bus.
AGP isn't a bus, it's a port. You won't be able to bridge them, but it's perfectly feasible for the chipset to provide more than one AGP port. -- <hpa@transmeta.com> at work, <hpa@zytor.com> in private!
