A pci device can read system RAM and other memory-mapped PCI devices
(such as display framebuffers) using DMA. In addition, a pci (but not
pci-express) device can snoop on pci bus traffic to other devices.
Typically, however, hard drive controllers will be integrated into the
chipset so the data is not on the bus.
