Yep. To have a bridge between PCI and AGP is not uncommon, but to have a
bridge fully implemented (support access from both sides) is actually
rare. Many times, there is a bridge between 2 PCI busses, but the bridge
only maps Host/PCI and PCI/Host, almost never PCI/PCI. It's logical,
nobody cares about PCI to PCI transaction in the mass market. However,
it's a violation of the PCI spec, but nobody cares about it either :-)
