Yah, 64-bit devices in 64-bit PCI slots could do 64-bit addressing
(assuming the PCI-Host bridge supports it). 64-bit devices in
32-bit slots could also work if the device and the PCI-Host bridge
supported Dual-Address-Cycle.
Really, it all depends on how lame the system's PCI implementation is.
But bus_dma on the i386 port currently only supports 32-bit addresses.
